That's more like it... the chargers are pretty solid.
The regs out in the battery box get abused and contaminated.
Let me know what you find.
Keep in mind a good washing in warm soapy water with a nice blow dry can
help in getting battery residue off the Regs.

I've done the same with my Jetta and it's not too bad. I've heard of others
packing the rack with grease and capping the hose fittings but I think the
weight of the grease would be a concern.

Listers,
This is a survey of sorts.
Three things :
1. If you DO use a spam-intercept service such as Spamarrest, please email
me PRIVATELY to let me know that you do. (See below for address info)
2. If you DO NOT use a spam intercept service, and think that all EVDL
members should be asked to NOT use a spam-intercept service on the
address they use with the list, please email me PRIVATELY with your views.
See below.
3. If you DO NOT use a spam intercept service, and think that whether a list
member uses a spam intercept service should not be anyone else's concern,
also please email me PRIVATELY with your views. See below.
Again I emphasise - please DO NOT REPLY OR POST BACK TO THE LIST,
but rather email me privately with your response.
To form my private email address please assemble the tokens below as
follows :

Personally, I don't care if they get my email or not.
Heck as far as I know, some of these "services" could be spam address
collection bots just waiting for me to "opt-in" by responding.
I think spamarrest, et al. are a stupid idea. They are used by lazy
people to force others to solve the spam problem so that the recipient
doesn't have to put the effort into creating filters.
What the heck is this? IO certainly don't want to verify myself to

IS he the list manager or just a subscriber?

If I can get someone to sell me a not-too-outrageously-priced
144V+/500A+ controller, I'd be willing to sell a Curtis 1221B. IIRC,
the C series have an annoying whine at low amp draw, so you may want
the B over the C anyway.
So, does anyone have a beefy(er) controller that I can buy off ya to
get this chain going?

Pasadena loses electric car fleet
PASADENA, Calif. (AP) - The eleven electric cars that once made
up part of Pasadena's city fleet have been reclaimed by their
maker, Nissan.
A Nissan spokesman says the carmaker had no choice but to take
away the zero-emission cars that had been leased to Pasadena
Water and Power for five years.
He says that they were brought into the country on a test program
under an agreement with customs officials that demanded their
destruction or return after a specified period of time.
And that that time has come.
Nissan crews reclaimed the vehicles Wednesday, after an
unsuccessful attempt to take them off Pasadena's Public Works lot
earlier this month.
That earlier time, city officials and environmental advocates
stopped the repo crews.
City leaders then tried to work out a new lease or a purchase
deal with Nissan.
But yesterday, the cars were gone and the city officials conceded
defeat.

was 2 Curtis 72V 400A peak controllers fed from a single pot box.
Not a sports car, but adequate.
For reverse they disconnected one motor and reversed the other one
This was stupid and cheap.
I only received a single Curtis controller with the two motors
connected in series
That would be a *real* dog! It will work like a car stuck in 1st gear
all the time. You'd go better with just one motor powered, and the other
removed completely! :-)
I have looked at the published pricing for another Curtis 400A
controller and also a Zilla 1K. The Curtis is at least 60% of the
cost of a Zilla w/hairball and would still only give me 400A peak
power.
The Zilla is a much nicer, more powerful controller. It also has options
to drive a pair of motors series/parallel, which would be a great setup
in this car. Series/parallel switching gives you an electric 2-speed
transmission.
But if economics are important, a second Curtis can probably be found
used at a good price. Even with the Curtis, I'd add the extra contactors
so you have proper reverse.
I am thinking about changing from 12 ea 6 volt batteries to 12 ea
12 volt batteries putting the system voltage to 144V
This would be a good way to go fast, but cut your battery life and range.
The 6v batteries are great for low cost and good range, and last longer
than anything else you can get for anywhere near the price. Their main
drawback is weaker accelleration, and the need for cleaning/watering.
The latter is a BIG drawback in the Tropica, as they made no provisions
for battery maintenance.
If it were me, I'd try 6v *SEALED* batteries to get rid of the
maintenance headaches. If life and range are important, use the Deka gel
cells. If performance is more important, use AGMs.
If I put the motors in series on the Zilla, could I put the fields in
series and then run both armatures through the reversing contactor to
get a reverse on both motors?
Yes. But you can do this with a 72v pack, too. Wire the motors in
parallel. They act more like a limited slip differential (better than
series). One Zilla can provide more current than BOTH Curtis
controllers. Your reversing contactor can reverse either the paralleled
fields, or the paralleled armatures.

Another weekly paper in town, The Anchorage Press, has been working on a story
for a couple weeks now. Thanks to those that responded to Monica's request and
contacted her with EV input.
Yes, Monica called me and we had a very good discussion about EVs. Great
job, Mike, on all the positive PR for EVs you're doing up in Alaska.
John, I haven't heard from any of those guys. You'll have to make the trip
back to Alaska for another class ;-)
Email me your phone number again, and I'll give it to the guys so they
can get in touch with you.
See Ya......John Wayland

Rich,
How important is power steering to you and who will be
driving this truck?
My US Electricar S10 has a problem with the DC/DC converter
and because I still want to drive it until I have time
to fix it, I disconnected the power steering pump.
(aux battery is used in deep cycle mode)
It is steering fine for me.
Actually it makes me cringe every time I see someone
grind their tires by turning the wheel while at standstill
only because the power steering allows it.
Without power steering this is not possible, but I have no
trouble turning into tight parking spaces, it is a matter
of driving slow and turning quickly.
I do not know about manual replacement , but I bet there
are either aftermarket or OEM Chevy/GM parts that fit, if
necessary from other trucks/SUVs.

Subject: Power to Manual Steering Conversion
I'm working on a '94 S10 that came with power steering. I was told at
the auto parts store that '94 S10's came standard with power steering
and that they didn't carry any replacement manual gears. Does anyone
know of any other make and model that would swap easily.

There's always the mysterious bad guy too. Hope the city pursues Nissan on this
one, sounds suspiciously like when Ford tried to claim to the Sacramento Bee
that their electric Rangers had to be crushed because they had received a
safety waiver from the NHTSB. That was probably the lie that forced Ford to
negotiate, maybe if Nissan's lie is exposed they will negotiate as well.
Ask Nissan to produce any customs documentation, or at least give the customs
officials' names that "demanded their destruction or return." I'd be willing to
bet they can't come up with a name or a document.
A Nissan spokesman says the carmaker had no choice but to take
away the zero-emission cars that had been leased to Pasadena
Water and Power for five years.
He says that they were brought into the country on a test program
under an agreement with customs officials that demanded their
destruction or return after a specified period of time.
And that that time has come.

To used this bearing splitter, you still need a two very hard fine thread
rods and cross bar with centers to push against the motor shaft. Some large
2 jaw pullers come with these rods and centers to fit bearing splitters.
The centers have either a inset or a pivot point so as not to damage the
shafts.
My shaft has a countersunk 3/8-16 screw bore, and it's the wrong size
for the pivot point. I was thinking that I could put a 3/8 butter bolt
in this hole, with a hole drilled in the top of it's head that is the
same diameter of the base of the pivot cone. Fill it with grease, and
go nuts.
A lot of times, you can get by without using the pulling rods, if the
bearing splitter can push against the item that is behind the bearing
without damage. I will sometimes will use wood shims behind the bearing
splitter to prevent any damage.
This makes sense. But, one bearing is right next to the end of the
comm. I don't know what the end of the comm is made of, so I'm not sure
if it's okay to use it as a pressure point.

Rich Richtmyer from the Anchorage Daily news called me Wednesday and wanted to
do an interview on the Electrabishi. I had a little time on Thursday so I met
with him at my office over lunch. He was kinda ho-hum asking a few questions,
why'd ya do it, where'd ya get the parts etc. etc. Then I took his camera man
for a drive frst, and then Rich. It was kinda embarassing I was all set to
burn the tires and when all that came out was a little squeak. Then I
remembered I was set to econo mode at 300 A. Whipped out the Palm Pilot to
change the settings and the camera man saw me type in 1000 (into the Amps input
prompt) and was amazed that it barked 'em with 300 A and I was changing it to
1000A. I think he took more pictures of me working the Palm Pilot than
anything else. After the rides though came all the detailed in depth
questions. I suppose he didn't tackle the numbers on the
cost-benefit-analysis, but after all it was only an hour interview including
the two rides.!

On another note from Alaska we just had our first AkEVA meeting on Friday.
Only 4 people turned out but there were another 5 that I know would have made
it if they were not out of town for work and pleasure. (Hey Dean, stop lurking
and jump on ;-) We had some good discussion about registering vehicles,
batteries, AC/DC questions etc, etc. Some of the people on the distribution
list include my Battery provider, and electrical/electronics recycler, the
Alaska Segway dealer, and hopefully Waylands racer friends at his companies
office in Anchorage. ( John, I haven't heard from any of those guys. You'll

On the DE, there's a large fan, and the fan actually *cradles* the

Hey Eric
Do you have access to an acc/ox torch and pair of prybars? Because that fan cones back over the bearing this might be the best route. Remove the rubber seal (if it's the rubber type of seal) and set the armature on it's comm so the fan and shaft stand staight up (I have holes in my benches to do this). Take the prybar pair and set them behind the bearing in between it and the fan. Take the torch and heat up the inner bearing race that sits on the shaft, this needs to be done quickly with a really hot flame, or the shaft will heat and swell. A lot of the time the weight of the prybars will pry the bearing up without any preasure needing to be applied. Do not try to pry against the fan as it may be just plastic. You are looking to swell the race up to have it just lift loose and must use high heat and work quickly.
As a matter of fact, my oxy/acet rig is about 4 feet from the motor =)
I have a fine-point nozzle for precise heating.
The fan itself is plastic, but I don't see any way that the pry bars
_wouldn't_ put pressure on the fan, unless you mean that the weight of
the pry bars alone is okay on the fan.
As an alternative, can I heat up the inner race, and simply pull it off
with my (leather welding glove adorned) hand?
Those split type bearing pullers will not work on this. I use a two armed push / puller that I grind down thin on the hook section to fit these tight fitting areas. I also torch off a lot of bearings as I descibe. Give a call if you need to go over things better.
I have a 2/3 jaw puller, and I imagine I can grind them down, but I'd
rather not.
Hope this helps

Hey Eric
To answer your question, yes the weight of the 2' prybars is most the time
enough to move the bearing once heated. You can use a little force if this
doesn't happen though. If by myself I'll use my elbow on one prybar while my
hand pushes the second one. I have the torch in the other hand and focus on
the inner race with a hot, focused flame. This should only take a minute to
do. If it don't work let it cool and try again. Just don't keep on it if it
doesn't do it. As far as glooves go I'd opt for anything you could use as
leverage vs trying to grab it with a glooved hand which would offer no
leverage. Besides This needs to get really hot so unless you got really good
glooves you'll be playing hot potato big time.
PS: This lets out some good smoke just so you know.
If you think this is bad try removing that plastic fan without breaking it,
LMAO!
Hope this helps

That will work for one end, but the other end is actually cupped by the
plastic fan. Plus, I hate to spend $20 + shipping for what is
(forseeably) a single-use item. I need to see if my neighbor the tool
hound has one of these.

Carmaker or Tech Start-up?
More forward-looking was the Connaught Type-D GT. This company is
new, but it has applied the respected Connaught marqueknown for
1950s Grand Prix successto a technically unique luxury
four-seater.
The designers goal was to build a high-performance 2+2 with
best-in-class space, performance, and fuel efficiency. The £64
500 (US $122 000) coupe is powered by the companys own tiny 2-L,
supercharged 300-hp V10. Fabricated from laser-cut stainless
steel with an aluminum body, it weighs just 950 kilograms (2100
pounds), hits 170 mph (274 km/h), and still delivers 18 mpg (12.8
L/100 km). Just 100 cars will be sold.
Next years hybrid Type-D will use lightweight
supercapacitorsnot heavy batteriesto provide a claimed 35 mpg
(6.7 L/100 km), and a subsequent version adds cylinder
deactivation to raise mileage to 50 mpg (4.7 L/100 km). As
Connaught cofounder Tony Martindale said, In effect, you get a
highly luxurious and spacious 1.0-L five-cylinder hybridexempt
from the congestion charge. Bold claims, for sure, but Connaught
seems as much engineering start-up as car company. It holds 23
patents; only 17 are for automotive technology.
