That's encouraging. Are the spines fairly standardized? Or does every
manufacturer invent his own to force customers to buy replacements from
him?

I think there are two reasons for this. One is that the motors typically
have *NO* cooling; they are sealed with no fans and no ventilation
slots. These could be added, of course. Cut a couple holes in the case,
and add a blower.
The other is that they can specify a smaller motor when they know it
will never run long periods of time. A given size motor might be rated 2
HP continuous, but you can get 10 HP for 5 minutes.

Interesting. I would think that spines should *never* fail if designed
right.

Yes, they do. They are quite common in lower speeds (up to a couple
hundred rpm), although some can run fast enough for freeway speeds with
normal size car tires.

Maybe they just hard-start these motors with nothing but a contactor
between them and the battery. That would produce killer starting torque.

The Europeans do indeed have higher standards. Also, more and more
high-end vehicles are coming with HID headlights which are a completely
different story.

Putting an actual 14v on a 12.5v sealed beam headlight will provide more
light; but also a 10:1 reduction in life!
G'day Lee, Mark and all.
In most of my (ICE) vehicles I've rewired the headlights with a relay
(quality Japanese brand) controlled by the old headlight wiring, and a new
chunky wire from B+ to the relay, and new wiring loom for the lights.
Quartz Halogen lamps complete the upgrade (480W of high beam on my work
truck with original [sealed] headlights replaced by aftermarket headlights
in the same frames).
I'm probably overheating the lamp assemblies, but in the 10 years since I
did the upgrade I've had as many broken lenses as lamp failures (rocks off
the roads) so the over-driving of the filaments in the lamps has been a
non-issue for me.
I persuaded one of my former employees to do the same upgrade on his van,
for the same cost as adding driving lights, but more work to do it. Next
night he headed 400km away into the dark of a West Coast (of Tasmania)
winter night. I got an SMS message from him the next day "I guess you knew
that guideposts throw shadows?"
Of course, the amount of difference depends on what was there before...

Hey Lee, all
They are all standard and all lifts use this same spline or the larger spline
from Clark to Raymond to Yale. These are fan cooled and one can feather the
contols. Although it's usually full on for most drivers. guess another factor
can be added by bad roller on the lift tracks, and mechanics failing to use
proper lube if at all, ect. Most of my customers fix when broken only, you
know, lol. If you'd like I'll throw some feelers out as to what they cost new
/ rebuilt and also to keep their eyes out for used unit's. The nice thing I
guess, is these splines are pinned and easy to replace and retail around
$50.00. I'll post a how to remove spline and fan section at the site the next
time I do one.

Jim, I just tried calling Chip Gribben on his cell for an update. I am
really anxious to see a new member of the 100 mph club. That would be one
more feather in the cap let alone his second place position on Drag Times
dot com. Keep them votes a coming. By the end of the month the lead by the
three electrics will probably be beyond any figures they have ever seen.
Even if they are aware that it is just a drag queen contest, oops, I meant
prom queen contest. Well they are all drag cars after all :-). Just having
fun with you all. Anyway the sheer number of votes will make them think that
at least people in this sport are very dedicated and they are very right to
believe that. It's a fact, Jack!
Anxiously waiting,

Mike,
USAA will let you call up and put a vehicle in a "storage" mode. This means
they'll leave it on your policy but not charge you premiums, or cover you in
an accident. If you've already paid a portion of the preium that you
haven't use in the 6 month period they'll prorate you back the premium.
This works good for the military folks. I used to be on a ship, in for two
months out for two months. I'd call up and tell then the truck would be
stored and not driven and to basically turn off the coverage.
On my Mitsu I called and put it on the policy, dorve it to the scales, then
called the next day and put it in storage mode.
Mike

I asked Alltrax if this would work. They said no, because the controller would
"see" the total voltage and fry. I don't know if that is a
difference between Alltrax & Curtis, Lee Hart and the Alltrax people, or just
excess caution on Alltrax's part. I'd be interested to see if this has
actually been tried by anyone, and if so, the results.

It could work, depending on how you wire it. The Curtis controller
switches M- (the negative side of the motor) between B+ and B- (the +
and - of your 48v pack). The positive side of the motor is normally tied
to B+. You can add a SPDT (Single Pole, Double Throw) contactor to
switch your extra batteries into the positive side of the motor. Try
this: <snip>

Hi Darin,
This has been kicked around many times. I can't
think of anything worse than an EV enthusiast with an
awesome emission-free rig getting plowed into by
someone, and getting compensated at 25% the cost of
their conversion.
I have a stated-value policy in the amount of
$8,500 on my Civvy. All I needed to do was prove the
value of the conversion/parts. I'm meticulous about
saving receipts! Allstate was the only game in town
who would let me insure a rig I converted by myself.
Amazing that these insurers are getting hammered by
global warming (tremendous losses), yet they won't
insure a product that alleviates it to some degree!!!
Not all Allstate affiliates will do the
stated-value policy, and not all Allstate affiliates
will insure a 3rd party conversion. Fortunately,
there are 3 in my town, and one of them does. Which
reminds me, I really need to write a thank you note.
peace, and good luck with the search...

Does anyone on this list have any information as to when this event started.
I had heard it got moved up to Saturday night but when you go to the Moroso
Motorsports Park web site
http://www.morosomotorsportspark.com/Newsite/Default.asp it bounces you back
to the NEDRA site with the incorrect information. I know the NHRA web
master, Chip Gribben, was locked out of the site so he could not update it
but someone on the right coast must know the schedule. Please share your
information. Waiting to hear of Matt's new times. It is 9:30 PM there.
Matt's lead on the former first place car is getting embarrassing. The
former first place car on dragtimes.com was a Subaru SVX LSI which ran a
14.534 to Matt's bested time of 14.274 and wasn't this his very first time
at the track with an unproven car? Minds WILL be changed forever.

Lee,
There isn't much space to work with where the 1221 is mounted. So a heatsink
or fan may not fit in there. I'll check with Ralph about a cold plate. I may
need to relocate whatever controller ends up "in charge of" the van.
The other thing is that the controller was installed in the van in 1995-96 as
a reconditioned unit. The van's odometer reads about 13,000 kilometers. So
whatever portion of that mileage has been logged since the installation has
been done with inadequate cooling for the controller.
Since I purchased the van last year there have been a few occasions where the
controller reduced current flow when it became too hot. However, a couple weeks
back, a strong odor of burning electronics permeated the van without a throttle
back. The controller was too hot to touch, the drive motor was merely warm. I
made it home but that's about all I can claim. The result? A vote of no
confidence in the controller. I won't venture out in the van until the
controller can be inspected, repaired, or replaced. So I'm mulling over the
options.
Lee perhaps you have seen this particular Electra Van. The original owner was
the State of Minnesota. Eventually they donated it to Mankato State University
where 2 students ultimately installed roof top solar panels in 1996 or so. Then
the van may have languished there until an Indiana based golf cart shop owner
purchased it from the university a couple years ago. I purchased it from him
last May.
Overall its in good shape for its age, except the panels were a total loss.
The panel platform is still on top of the van and I may put new panels back up
there at some point.

Why not just add a fan, heatsink, cold plate, or other cooling to it?

When I insured my Civic (liability only), I told the agent it was an
electric conversion. She was silent for a moment, then said something to
the effect of "I don't see anything here about that." AFAIK, she wrote the
policy as if it were an ordinary Civic. I'm not sure that was the right way
to go about it, but I didn't fuss.

Huh. The safety switch is OFF. What's the point of having it then?

My old Cableform controller was a series type 144 volt controller that was in
series with a 180 volt pack. The battery negative went threw the controller
and than to the motor. The battery positive went right to the motor. The motor
name plate voltage was at 165 volts.
The SCR's and diodes were all rated for 600 volts, but the control, trigger and
accelerator circuits were rated for 144 volts. Cableform modified this unit by
just adding large heat sinking power resistors to drop the 180 volts for the
144 control circuit.
The 180 volts was connected to the 800 amp 600 volt SCRS, 250 volt rated
capacitor bank, free wheeling diode and anything else that was rated over 180
volts. A tapped off the 180 volts with a fuse going to the power resistors
voltage divider power the lower voltage control circuits.
This unit ran for 25 years, before I replace it with a Zilla.

Subject: Re: IS this a good idea (batteries in series with controller)
I asked Alltrax if this would work. They said no, because the controller
would "see" the total voltage and fry. I don't know if that is a
difference between Alltrax & Curtis, Lee Hart and the Alltrax people, or just
excess caution on Alltrax's part. I'd be interested to see if this has
actually been tried by anyone, and if so, the results.

It could work, depending on how you wire it. The Curtis controller
switches M- (the negative side of the motor) between B+ and B- (the +
and - of your 48v pack). The positive side of the motor is normally tied
to B+. You can add a SPDT (Single Pole, Double Throw) contactor to
switch your extra batteries into the positive side of the motor. Try
this: <snip>

how about running an 8 volt battery AND a 6 volt in series for your aux
system? Then you could have 14 volts.

What bothers me about running off just a battery is that it is only 12
volts. Too dim of headlight for me. My work-in-progress will get a DC to DC
that runs an output of 14 to 14.5 VDC no battery. This is the level present
ICE cars run at and is the voltage the headlights and accessories were
designed to run at.

Can you name what state you live in and who those 3 are?
Maybe some of us can support those agencies with our

Actually, that looks like Cam-loc connectors for travelling stage/music

As with much in life incompetence is not a legal defense. The agent's "mistake"
may open you up to liability and lack of coverage, but that is only IMHO. I may
be full of it also.

When I insured my Civic (liability only), I told the agent it was an

the effect of "I don't see anything here about that." AFAIK, she wrote the

to go about it, but I didn't fuss.
