1989 GMC : 3500 Vandura Item number: 320138527359
I noticed these 2 vans are still relatively cheap -
$1500 / ea. One is NiCD. One is NiMH. Lots of
views, few bids. Anyone know the history on these?
Supposedly (according to the auction) the NiCDs are
still good and hold a charge. Still, the vans are
listed as not running.

I hope this forum that just popped up, isn't some sort
of scam, it might relieve you seasoned EV'rs from the
postings of us newbies, that don't search the archives
quite as well as needed (Yes I'm guilty). I'd hate to
see some of you guys leave the EVDL list, due to all
the new postings from us newbies. Please keep in mind
most of us are all working towards the same goal, to
be driving a EV rather than an ICE and for me, getting
the word out to more and more people about EV
conversions can only be a good thing.

Neon sound like a good way to go. Can you give an example of the neon unit?
I did a quick perusal of Digi-key and came up with a min. order of 200
units.

Funny this should come up the day after I took a chance and bought a
"Flight Systems universal card" off Ebay. It'll take about a fortnight to
get to me, the auction photos didn't state an operating range.
It actually calls itself "EV-1 COMBINATION CARD", model seems to be
13-ECOM-E1 and the lable also says that it is a direct replacement for:
IC3645OSC1A3
IC3645OSC1B3

Anyone know what the highest voltage is that this replaces?

Hello from Tempe AZ,
My name is Brian and this is my first day on this list. I have been looking
into converting a compact wagon such as Ford's Escort over to electric. I have
extensive experience working on IC powered cars, so the mechanics of converting
a car is not terribly worrisome. The electrical side is a bit more of a
challenge for me. I have started putting a spread sheet together so that I can
make changes to my design / designs and see the theoretical results. If any of
you are interested in taking a look at this spreadsheet, here is a link
http://www.box.net/shared/2st7b53bqe
This version of the spreadsheet is not finished, and as I learn more, I am
constantly going back and fixing mistakes. However, any advice is welcome. I'm
pretty inexperienced with this type of car, so I am sure that mistakes exist on
this version of the spreadsheet that I am not yet aware of.

A neon bulb across the contactor will be lit when the contactor is not

contactor is shut.
I think there is a way with a diode to make it the opposite. Neon bulbs
can handle the high voltage and don't pass enough current to effect
anything.
I have neon lamps in my EV. One is across the controller input (lights
when there is power to the controller. One is across the charger output
before it bridge rectifier (lights when it is applying voltage), and one
lights when the auxiliary circuits (right now just the heater) has pack
power.

For a panel mount, I use Digi-key's 67-1167-ND ( red) or yellow or
green. You would need a dropping resistor of about 6000 ohms and 3 or
more watts to give you about 20ma through the LED.
An NE2 or equivalent neon lamp only draws a few ma for full brightness,
so a dropping resistor is all you need. The total power dissipation is
under 1/2 watt. As high voltage low current indicators, neons easily
beat LEDs.

Hello, My name is Robert Green. I just saw your EV on
austinev albums and thought I'd invite you to a new EV
conversion community I'm starting up. The point of the
community is to organize conversion information, help
facilitate communication between DIYers like yourself
and others and bring in parts vendors and fabricators
all to a single location to help everyone's projects
out. The end goal is to have guides and kits available
for most makes and models of standard cars and
community support for those attempting their EV
conversions.
You have very valuable experience and information that
I think could seriously benefit others and I think you
will find more information valuable to you in the very
near future. What I'd really like is for you to
introduce yourself or post a little info about your
past or existing projects to help me jumpstart this
database. Several admins will be checking the site,
sorting and grouping the posts and data to make sure
the site is growing in ways constructive and helpful

accessible for more households to start driving
electric.

Neon lamps are a commodity item, used by the millions and carried by
thousands of stores. Even hardware stores have them. I guess light bulbs
aren't "electronic" enough for Digikey. :-)
See www.jameco.com part#s 1765849, 215803, 215811, 215830, 1585485 (all
panel mount neons, including holder and resistor, $1-$2 each), or part#s
27351, 210315, 1766064, or 1770744 (bare bulbs, $0.29-$0.57 each).
Or, see www.mouser.com; they have literally hundreds to choose from.

Well my motor and old engine are both down at a local machine shop
getting an adapter made. The guys who work there are excited about it
and said they like working on "cool projects" :D also I was quoted a
far lower price than it would have cost to get my tranny shipped to
the lower 48 to have one made.
Living on the coast in a fishing town seems to have it's advantages
for building and EV, with all the aluminum boat welding shops, machine
shops that are used to all sorts of adapting and all the boat supplies
like high current cabling, lugs etc.
I just put up my website to document the conversion, www.helixev.com

So, I'm trying to figure out how to mount my big motor (which I think
we've agreed is a sepex motor) to my transmission.... it's got a
nice adaptor on it now which will alledgedly bolt directly to a Borg
Warner T-10 transmission with a chevy V-8 bellhousing. Clutch and all
(it was in a 1967 corvette previously)
But, I've got a little 4 speed mazda transmission (Ford Courier
pickup). I thought of three options....
1) Fit chevy bell housing to mazda transmission, and try to make chevy
clutch disc connect to mazda input shaft, and mazda slave cylinder
activate the chevy clutch fork.
2) use a chevy transmission, and get a new driveshaft made. I thought
since the S-10 is a popular EV conversion, some of your migth have
ideas on what sort of transmission might work for this... do any of
the S-10 transmissions bolt to a V-8 engine?
3) redo the adaptor, to bolt to the mazda transmission bell housing,
and use the mazda flywheel and clutch setup.
Suggestions?
Thanks

Scam? Like what?
The facts are:
- Most people on this list would like to see EVs go mainstream.
- Allot of people on this list have no idea how to search the archive or
where to go to do it, nor do they wish to take the time to figure it out
when a web forum offers the convenience right in front of their faces on
every single page.
Mailing lists of this size are unwieldy and antiquated - and not readily
embraced by the AOL/MySpace generation of internet users.
I used to run a fairly large mailing list and am familiar with many aspects
of operating them, but I hate the snot out of the format now. Instead of
just browsing through threads adressing subjects of immediate interest or
being able to easily and conveniently search, I end up having to press the
delete key endlessly on stuff that I am not the least bit interested in.
Mailing lists are best for immediate polling of the knowledge base of it's
users or for sending alerts, but when it comes to the basics, we need
something better. I'm not complaining about the quality of the discussion
here, but merely the shotgun disorganized nature of the format. Until
something better catches on, it will do. But I really hope something better
catches on!
If we wanted to make EV conversion easier and more mainstream, doesn't it
make sense to make the access to the information meet the same criteria?
Someday, I will be a seasoned EV'er, and I probably won't be talking about
it much here except to redirect people to a more convenient format.
I have registered on the new forum and hope to see many others do so as
well. Continuing to stick to this list as the sole means of technical
support is a Luddistic insistance on not progressing the cause.

I need to mount the speed sensor on an ADC 9" double shaft motor. I'm

that someone has already built a bracket to mount the stock sensor at
the free end of the tail shaft. If you have pictures and/or dwgs and
measurements of such a bracket, please drop me a line.
I found that a 2 1/2" PVC pipe cap fits very snugly around the raised ring
at the base of the tailshaft on my Impulse 9" motor. I used a dremel to
cut a hole for the sensor pickup and secured it with two sheet metal
screws. This was a quick and dirty hack to get me on the road, but it's
been in place for over a year now and is still holding up. In fact, I had
to use a small hammer to remove the PVC cap to make an adjustment to the
pickup.
I didn't "engineer" a proper solution because the other drilled/tapped
holes on the motor face were covered by my motor mount :(

I can't read your post, but I saw the video. If you look closely
you'll see an E-Com!
But I have to admit, is Toyota trying to have people the Prius's
design. I mean, the way it already is, it doesn't look so great. Did
they really need to add the frilly flowers and birds?
Toyot says that they're not using lithium batteries but just a bigger
NiMH pack, Maybe the whole patent issue with Cosaby and Panasonic is
over or the patent has expired?

If I remember correctly, they're just using two strings of the 6.5Ah
Panasonic prismatic NiMH batteries - more or less two of the existing
Prius battery packs in parallel. (So not violating any Cobasys patent
licensing.)
The stated 13km range is pretty puny though, I don't think plugin
hybrids will gain traction (unintentional pun) until the electric
range is more like 50kms. Which pretty much means lithium batteries.
(It might be possible with lead, but with all the ICE weight in there
as well it'd get way too heavy.)

Naw, just another one of those who don't like the EVDL's simplicity, but this
one used one of our own resources for recruitment spamming. I don't think it
will dilute the intellectual concentration here because the "old guard" who are
doing EVs for a living don't have time to navigate a forum, just read their
inbox and respond or delete. Personally, I use the Yahoo "ev" group to read the
digests and keep my inbox out of the traffic flow.

It is political. we may want electric vehicles but
there are powerful folks who want to make them as
inconvient and unuasable as possible. It really has
nothing to do with saftey. Untill Toyota, Ford, GM
etc make electrics (which they will only do when
forced to) we will all have an up hill battle.

I drive one of the EV Rangers that Ford was forced to make (then publicly shamed
into selling what wasn't already crushed), so we *know* it's possible. They
could get just as much profit from the original sale of an EV as the ICE
equivalent, but Henry Ford, when asked about the low price of Model T's, said
something like "I could give them away and make all my profit on upkeep" -
without an engine or transmission, what would keep the dealers afloat? I have
to admit, I do feel safer in a pickup at 70mph than an NEV on busy
streets...but then, I don't bicycle very often either!

You may not need any extra reduction.. What motor(s) were you
thinking of using? Series DC motors have a whole lot of torque.
I'm currently doing an MX5 direct drive with two Advanced DC L91s,
6.7" series DC motors. Out of interest, here are some numbers..
The petrol engine has 140Nm of torque *peak*. Admitedly, it's pretty
modest for an ICE.
1st gear ratio is 3.136 : 1. Therefore, with a direct drive setup you
need about 440Nm of torque from an electric motor to have the same
torque as the ICE had peak - it'll actually be much quicker because
the electrics have such a great torque curve. 440Nm is quite feasible
from an 11" motor, or a couple of smaller motors.
The diff ratio in the MX5 is 4.3:1, which means the motor will be
spinning at a lazy 4000rpm at 100km/h, and top out (6000rpm) at about
150km/h - I can't imagine needing more than this.
If using an AC motor though, you'd probably want a 2:1 reduction
though since they generally rev much higher and have less torque.

do you have a special fixed reduction on your cycles or do your
motorcycle electric motors have
similar torque/rpm to the engines they replace

single speed harder and more expensive? i'm still in
the planning stages of a four wheeled vehicle but from
working on electric motorcycles i find single speed
easy while hooking up to an existing trany seems
harder? that gives me hope that an electric car is
not as hard as i'm making it out to be!

As it was recruitment for another souce of EV info, I wouldn't have
considered it spam; and even though I did not receive an email invite,
I'm glad you guys made me aware of it.
I've heard attempts at web based "EVDL replacements" (if you choose
to consider them that) have failed in the past, but don't see why they
can't co-exist and even complement each other.
The way some here speak of those new-fangled web based boards makes me
wonder if the EVDL's mission is being fulfilled to the fullest extent
possible.
The EVDL is currently like a secret handshake to new users. Just look
at the amount of people not "getting" the text only format and bugging
the hell out of the veterans.
I'm just glad that other forms of disseminating EV info exists.
YouTube videos of White Zombie to complement the stories here is an
awesome (cool, groovy, tight, sweet, [insert your generation's slang
for swell]) experience.
Here's hoping that Robert Green makes it, and/or that someone else
tries again if he doesn't succeed.
Still bummed I wasn't worthy of an invite though,

you can use range[km]=250 x capacity[kWh] / (mass[kg]^0.6)
or range[miles]=250 x capacity[kWh] / (mass[lbs]^0.6)
{same due to lucky cancellation , #km/mile = (#kilograms/lb)^0.6 }
comparison of various range formulas, graphs at
http://physics.technion.ac.il/~rutman/range.htm
the formula is based on real data from the evdl and there is spread
of results due to factors
not in the formula such as: aero coeff, regen or no, driving style
(e.g. avg speed), hilliness, peukert etc.
Uve's groovy calculation page is branched off

Here's a simple one. Cant remember how to figure out

Hey things are looking up in the world of Alaskan EV's. Don in Kodiak has been
driving his VW Golf now for a couple months, Dave
down in Juneau just took delivery of a ZAP Xebra a few days ago, You are
getting your adaptor plate ready to mount your motor,
Bart just moved his Super Beetle under its own power today :-) You gotta see
his "Range Extending Trailer" video on which he
towed THE (single) battery that moved his car up the road :-) And if I'm not
wrong Mike Golub in Fairbanks is working on a Geo
conversion.
Anyway, good job on the progress. If I were to make a recommendation, if you
are not already doing it, keep a detailed handwritten
journal. I kept a lose journal on my Mitsubishi and am starting to remember
little stories that I didn't write down that I'm soon
to forget, again. I kept real good detail of the parts, pieces and numbers.
But its the words and the story that I wish I had
written more about. So I have a little book I carry around for the Crazyhorse
Pinto Project. EVerything I do gets written down
(EVen the arrival of Jim Husted's "Pimped Out" motors :-). I can carry it in
my back pocket. The journal for the Mitsubishi was
a big 5 section spiral bound notebook and sat on the workbench the whole time.
Writing in that thing while I was a all grungy was
the last thing I wanted to do. This way the book stays with me and if I think
of something to write, its right there :-)

Anchorage, Ak.

Keeping a journal is a good idea. I prefer to have a camera handy and take
pictures as I go. Then, when it comes time to update my web site, I simply
scroll through the pictures and write about that particular step in the build.
I don't have an EV yet, so my builds are all IC projects. The documentation
works the same though.

Lot of replies about what lamp would work, but two things:
1) Wouldn't a lamp on the controller side of the contactor from B+ to B-
stay on a _long_ time, until the capacitor bank discharges?
2) Similarly, a lamp across the contactor could charge the capacitor
bank when the contactor is open, unless the leakage is enough to keep
the lamp lit.
Frank John wrote:
I'm interested in wiring indicator lamps to the contactor output (2 contactor
system) to show state i.e. open or closed. That means finding a small light or
lamp that works at pack voltage (120 VDC nominal). Mouser shows a lamp
(606-CM8-3995) that I think will do the job but I'm open to suggestions or
experience. Has anyone found an interesting way to accomplish this? Will the
lamp I mentioned work?

All this talk about low maintenance EVs versus IC powered vehicles. Is it
really so profound a difference? My wife drives a 98 Tacoma that has never been
in the shop for anything other than plugs, wires, air filters, oil filters and
oil. Shoot, I think the thing is still on its original battery. Wow, that thing
is 9 years old. Maybe I should replace it one of these days. We have never
serviced the brakes, and they show no sign of fading to this day. We have
probably spend about $100 per year on basic tune up stuff. Are EVs really that
much better?
Maybe if we were comparing EV maintenance to American car reliability. A Yugo
is probably more reliable than our 40,000 mile '01 Dodge 1/2 ton. What a pile
that thing is. Sigh. Poor American cars.
