The original setup uses deliberately undersized wire to act as a
resistor to limit starting current. This obviously has drawbacks :-)
Here's a simple circuit I used in my son's electric motorcycle. View it
with a fixed width font.
S1 R1
+12v___/_____/\/\________
| | |
|___/____| _|_
_____| / \ motor
K1 |_ \___/
|_ |
Common_________|_________|
S1 is the accelerator pedal or "go" switch. K1 is a SPST automotive
relay. The one I used has a 12vdc coil and a 40 amp normally-open
contact. R1 is a resistor chosen to provide a "reasonable" starting
current (I used a 2 ohm 20 watt resistor).
When you close S1, K1 will be off, so all the current flows through R1.
The motor current is limited to about 5 amps, which limits its starting
torque.
As the motor speeds up, the voltage across it rises. When it gets to
about 6-7 volts, K1 has enough voltage to pull in. This shorts R1,
giving you full power.
This circuit was very effective in keeping the motorcycle from pulling
"wheelies" on starting. Note: the resistor will get VERY HOT if
something prevents the motor from coming up to speed (like climbing too
steep a hill or something that prevents the wheel from turning).

Since ICE are doing this with oxy sensors there is no reason a sensor

In the old days, one method for setting the timing was to measure the
voltage directly on the commutator, using a pencil as a probe,
attached to a volt meter. This finds the lowest voltage position for
the load conditions at the time.

John and Deanne, I have repaired many melted posts on older batteries.
Somewhere I have the steel molds. They are easy to make, anyway. You have
to be carefull of an explosion by opening and blowing out the cell caps and
maybe putting a wet towell over the battery. Then you lead weld with a low
flame oxy acetylene torch. The real problem is in achieving or not
disrupting the seal to the battery case. Without a good seal, there will be
a continuous and ongoing corrosion problem. If the post is burned off down
into the battery too far or if the seal is destroyed, it may be better to
just replace the battery. As I say, I have done this repair many times, but
experts on this board can correct me if I am missing something.

Hi John, Jim and everyone,
I actually subscribed to C&D just so I could get the article and it
came in the mail yesterday!! At the time my daughter's class was
selling magazine subscriptions last fall so I said what the heck.
It's a great article. 4 pages with lots of pictures (I counted 16).
What Ted West wrote a great story and was absolutely correct when you
drive with your chin up in the Zombie. You don't have a choice. The
sucker throws you back in the seat so hard you literally can't move
your head forward as the car lurches from the line and accelerates
down the track. The car would be great for Astronaut training.
They emphasized the 772 foot pounds of torque at zero rpm which is
something alot of the gassers are impressed with.
But it's a great article as others have said. Roderick is in there
with Gone Postal as well as Father Time with Frankendragon and Otmar
with his Porsche. Jim is mentioned in the article. I can see the
Fiamp in the background of one of the photos. Even saw some of my
artwork gracing several of the pictures.
The opening photo of Tim doing a burnout in the Zombie with his eyes
fixed in a display of determination and concentration (there are
probably better words to describe it) is a great photo.
And the picture of John standing in his driveway with his garage, the
Zombie and California Poppy in the background with a couple guys
milling about the garage is perfect. It shows that NEDRA is a
grassroots backyard mechanic type organization and that we can build
alt-fuel cars that can blow the doors off the gasser muscle car
establishment. I also love John's expression in the picture. It goes
great with Tim's expression on the opposite page.
What a great article. I'm sure it will be available soon in the stores.
Great work John and everyone involved!

As a quick summery here on the Car and Driver thing.
I ran all over Redmond looking for a copy yesterday

The shop I've used had commercially made molds but they didn't know
where they got them. Anyone know where you can buy automotive
post casting molds? As George said, there's not much to them and
could be fabricated on a basic lathe, but I don't have the time, or
the lathe.

> Hi all

About every 2 or 3 months, someone (usually an EVDL newbie) posts a note
about these motors. We appreciate the thought, but they're of almost no use
to EV hobbyists, nor yet to anyone. They've been on offer for years and will
probably never be sold.
The reason is that no inverters are available for them. They require Siemens
inverters, which are never sold without motors. Unless you have a lot of time
and money on your hands and want to "roll your own" inverter - not a trivial
task - they're just expensive hunks of scrap metal.
If they were offered cheaply - say, $100 each - then it might be worthwhile for
someone to design a DIY inverter for them. But at the $2000 the seller is
asking, it's not worth the trouble.
Also, the output shaft is difficult to adapt to conversion use.
The only possible use for them would be as spares if you happen to own the
exact Ford vehicle which used them. Someone correct me if I'm wrong, but I
think these were used only in the early conversions which were performed on
Ford-supplied Ranger gliders by a contract upfitter. The name of the
contractor escapes me at the moment, but I think it was in the early 1990s.
Not many were sold, so the actual market for these motors is pretty much
just scrap dealers.

I had another thought that kicked into my forebrain during my morning
commute (which I normally spend ranting at other drivers and spilling
more coffee than I drink, but which today was oddly removed of traffic
or frustration).
Evaluate whatever axle you throw under that Pinto for c-clips -- if
you're thinking about changing axles, now may be a good time to plan
ahead. NHRA rules don't allow cars running tens or better to have c-clip
rear ends (break a c clip axle--lose your tire). Dunno about NEDRA. With
so many c-clip eliminator kits available that also provide big-bearing
capability, you should at least consider the options available.
And as to the point I was making about checking the net price to your
door, what I meant was: 1.) ship to mainland plus 2.) spline cut plus
3.) ship back to North Pole might be more than 1.) buy snazzy new parts
and 2.) ship to North Pole, ESPECIALLY if you can find a vendor that is
willing to do free shipping (may be tough to Alaska!).
I was poking around that Drivetrain Outlet website, and saw replacement
axles as low as $85 if you can backtrack to a stock dimension (maybe use
two short-sides to get the width you need?).
With the traffic I experienced (or rather DID NOT experience) on my
commute this AM, I am off to buy a lottery ticket. Perhaps a Tesla is
only a PowerBall ticket out of reach!

I also purchased C&D for a year to see this article. I used to read C&D for
about 20 years and they do have a talented staff. With this in mind I was
curious how they would present an area of the EV community without annoying
their major advertisers. Well they did it. No mention of practicality, range,
or anything mentioned for potential EV consumers. This article was written in a
way that would not detract interest of the general motoring public away from
fossil fueled transportation. I'm certain the Portland EV'ers mentioned the
importance of EV's for the well being of planet Earth along with allowing the
end user the choice and cost of "fuel".

Hi Ryan, I want to thank you so very much for sharing this information. I
already sent a copy to JW, FT and Otmar as well as friends in Croatia. I was
blown away that the article got mentioned on the cover as well as a nice
shot of White Zombie doing a burnout on page 10 which is the index to
Features as well as Up Front and Columns sections. Massively great press for
the movement! There is a photo of Father Time taking off on his drag
motorcycle with his white beard flowing out from under his helmet. Also a
picture of Otmar's car launching as well as a couple local Oregon cars. One
of the things I like best is a little inset above a picture of cars charging
at the Wayland Juice Bar. It says: "Powered by American Electrons" all on
the traditional red, white, and blue flag background. Yeh, sorry for the off

I was wondering if anyone could tell me where to find plans for a
contactor controller suitable for an EV. I looked pretty hard but could
only find schematics for small fans and things. Seems like one would be
easy enough to construct but I can't find anything for the 144v/1000 amp
area which is what Im planning on. Im no expert or even prob an
intermediate, but Ive had some electronics classes and should be able to
build it from a diagram if anyone has a good one. Or any other means to
control an ev other than the high priced controllers or a low voltage
one for a forklift (unless it can be beafed up, I doubt, or there is
industrial equipment that uses this high voltage and current?). Thanks.

Nice to see the Spring Safety paranoia is in full swing.
I am getting tired of it year after year.
It rains a LOT here in Seattle, I charge a completely un grounded EV off of
240..
I don't get shocked.. and I am asking to be totally vaporized any
second..Right???
According to the Safety Regs I should be Dead years ago.
Funny Why am I NOT????
The harder part is not too toss regs and safety procedures at the Newbies,
and explain why the hazzards known are not that hazzardous.
The last time I got shocked really hard was IN a grounded situation... I was
plugged into a "Grounded" Out let it was a public site...
The fact that the ground was not connected some wheres unseen.. Lit me up.
I was rather pissed off.. and then reverted to a non conductive screw
driver.. and continued on as if the EV was hotter than Snot. Yes I was
standing in a puddle of water.
I think the clearer question and solution is to make sure you don't have a
fault.. and to never get yourself in a situation that can kill you.
And never let the neibour Kids mess with your EV while it's charging.
Safety Every where or prudent solutions all the time.

Hi,
i ordered them, still on the way, i will let you know as list the test
results.
Nota that there is already good test results with powercheq, batteq test was
more unknow but now we know we must underate their use in EV batterie by 5
ratio :^)

Geezzz,, I thought that with all the Band Width on Li-Ion
that Bill Dube's anouncement that they were going to actually offer FOR
SALE a little Cube-Like 12V Battery, made up of A123 cells, would have
set the EVDL ON FIRE.....

The 8-place requirement limits your choices. That lets out the small and
midsize MPVs which often don't have more than 7 seats.
The problem is that some current large MPVs are quite heavy and have
surprisingly low payload capacity. This poses a signifciant challenge since
for most people lead batteries are just about the only affordable option, and
they're heavy.
Older (read : "ancient") VW Microbuses have been converted fairly
successfully. Newer Eurovans etc. seem to have blimped out pretty badly
and can be crushingly expensive to keep running.
Most people use an EV as a second vehicle anyway. Surely you don't haul
the entire family along on every trip. You may want to consider a small 2- or
4-place car for conversion, and keep your current ICE for the relatively few
occasions when you pile the whole crew in. Or maybe you could trade two of
the kids in on one newer, larger one. (Just kidding. ;-)

No conversion is impossible. Some are more practical than others. ;-)

A little more detail would help here like how much
range, speed, freeway, what you are doing with it, budget,
location, 8 kids or adults, ect.
I have been advised that my front wheel
>drive lumina apv is impossible to convert to an Ev
I'd like to know those reasons as I'd think it would
be good as the GM Dustbuster Vans were fairly lightweight at
about 3300 lbs iirc and had excellent aerodynamics so would
seem to be a good glider for 8 people? If it's just the
transmission then that can be easily fixed.
An aircooled VW Van EV could possibly do what you
want.
A fair number of Crysler mini-vans were converted by
them called T-vans. Also other reg GM, ect vans were
converted for Gov, Military and can be found with searching
Gov surplus actions as they are not normally wanted, could
get for a good price. Maybe someone on the list has one you
could buy?
Put an add in the EV for sale lists under wanted.
Check the EV Photo Album for EV vans as their owners may
know of more and a good place for a free add. Sometimes
these are mentioned here when coming up for sale.
Good Luck,
Jerry Dycus

While working in a local (Children's) hospital I plugged in a brand new
Hewlett-Packard
vacuum voltmeter, only to hear a loud explosion and saw smoke curling out.
Inspection found nothing but some dark smudges on the chassis.
Plugged in again, it worked!
Closer inspection with pictures in the manual showed that a 2 inch green
wire to
the chassis ground had vaporized.
The wall convenience outlet circuit breaker was 60 Amps, and the neutral
and hot
wires were swapped. Never trust a strange outlet until you have
verified the polarity.

A contact controller is a contact controller, the only difference for sizing
is getting contacts etc... that are rated for the voltage and current you
expect to experience. I am currently experimenting with a rectactor which
should be fairly beefy. I bought some big GE contactors and large diodes
off Ebay for about $200 total and am working off of an ascii drawing that
Lee Hart has posted on this list several times. There are some scanned
pages out of a book on the EV Yahoo archive with some schematics and text
for both Contact Controllers and Rectactors.
Note, I do plan on buying one of the expensive DC controllers, as they are
very nice. If you take a look at the old timers on this list you will see
that most of them have used contact controllers in the past and now use
modern PWM controllers. There must be some good reasons. Shoot, even Bob
Rice an old Railroad/Street Car enthusiest is not using contact controllers
anymore.
The rectactor that I am building I am doing, first for the hands on
experience, second because it will allow me to easily test different voltage
and current levels so I know which expensive DC controller best suits my
needs, and third because the expensive DC controller that I am guessing I
want has a very long lead time...

I was wondering if anyone could tell me where to find plans for a
contactor controller suitable for an EV. I looked pretty hard but could
only find schematics for small fans and things. Seems like one would be
easy enough to construct but I can't find anything for the 144v/1000 amp
area which is what Im planning on. Im no expert or even prob an
intermediate, but Ive had some electronics classes and should be able to
build it from a diagram if anyone has a good one. Or any other means to
control an ev other than the high priced controllers or a low voltage
one for a forklift (unless it can be beafed up, I doubt, or there is
industrial equipment that uses this high voltage and current?). Thanks.

The original setup uses deliberately undersized wire to act as a
resistor to limit starting current. This obviously has drawbacks :-)
Here's a simple circuit I used in my son's electric motorcycle. View it
with a fixed width font.
S1 R1
+12v___/_____/\/\________
| | |
|___/____| _|_
_____| / \ motor
K1 |_ \___/
|_ |
Common_________|_________|
S1 is the accelerator pedal or "go" switch. K1 is a SPST automotive
relay. The one I used has a 12vdc coil and a 40 amp normally-open
contact. R1 is a resistor chosen to provide a "reasonable" starting
current (I used a 2 ohm 20 watt resistor).
When you close S1, K1 will be off, so all the current flows through R1.
The motor current is limited to about 5 amps, which limits its starting
torque.
As the motor speeds up, the voltage across it rises. When it gets to
about 6-7 volts, K1 has enough voltage to pull in. This shorts R1,
giving you full power.
This circuit was very effective in keeping the motorcycle from pulling
"wheelies" on starting. Note: the resistor will get VERY HOT if
something prevents the motor from coming up to speed (like climbing too
steep a hill or something that prevents the wheel from turning).

Try Waytek Inc <www.waytekwire.com>. I think what you want is what they
call a "stud type junction block", stock# 47210, 47211, 47212, or 47213.
3/8" bolt, black or red plastic body that mounts to bulkhead, rated
250 amps continuous.

Rich
A friend of mine never wears ( and, has never worn) a seat belt. He's
asking to be killed any second, right? But, he's never been even slightly
injured in an accident.
In fact, the only people I know who were injured in accidents WERE wearing
their seat belts. Boy, were they paranoid!! They would have been better
off not wearing them.
According to the experts, my friend should be dead years ago. Funny, why is
he NOT????
You never wear a seat belt, do you, Rich ? I think the clearer question
and solution is to make sure you don't have an accident, and to never get
yourself in a situation that can kill you.
And, don't ground your car while charging it either. That's another stupid
idea.

Nice to see the Spring Safety paranoia is in full swing.
I am getting tired of it year after year.
It rains a LOT here in Seattle, I charge a completely un grounded EV off of
240..
I don't get shocked.. and I am asking to be totally vaporized any
second..Right???
According to the Safety Regs I should be Dead years ago.
Funny Why am I NOT????
The harder part is not too toss regs and safety procedures at the Newbies,
and explain why the hazzards known are not that hazzardous.
The last time I got shocked really hard was IN a grounded situation... I
was
plugged into a "Grounded" Out let it was a public site...
The fact that the ground was not connected some wheres unseen.. Lit me up.
I was rather pissed off.. and then reverted to a non conductive screw
driver.. and continued on as if the EV was hotter than Snot. Yes I was
standing in a puddle of water.
I think the clearer question and solution is to make sure you don't have a
fault.. and to never get yourself in a situation that can kill you.
And never let the neibour Kids mess with your EV while it's charging.
Safety Every where or prudent solutions all the time.

So let me get this straight, you'll pay me to pick on

into that 8^P How's something like this...
To my buddy Hump
I knew you'd never get a Siamese motor so I sent you
this!
Hell I bet I could have hours of fun with something

I'll see what John says being I'm probably just worth
