Going to need more info than that.
- Pack voltage currently, vs. regular pack voltage
- Voltage of aux. battery/DCDC converter.
- Is main contactor being pulled in when you power up the vehicle?
This will get us started.
(;-p
Thinking about converting a gen. 5 ('92-95) Honda Civic? See
http://home.budget.net/~bbath/CivicWithACord.html for DVD and tons more info!

Would you still drive your car if the tailpipe came out of the steering wheel?

Subject: [EVDL] 85 VW Cabriolet Newbie, please help! m(_ _)m
Hi All,
I spent a full 7 days in Santa Cruz last week working side by side with Mike
and Shari at Electro Automotive to finish repairs on my 85 VW Cabriolet
conversion. The good news is the vehicle was operating nicely when I left
Santa Cruz on Saturday with the VW on a flatbed uhaul trailer. The bad news
is that once I arrived in Los Angeles, I backed the VW off of the flatbed
trailer, made two small circles in the parking lot, and proceeded to park
the car. I then left the VW in the parking lot while I returned the uhaul
trailer. When I returned to the parking lot to make the final 2 mile drive
home in EV glory, the VW would not move an inch.
m(_ _)m
This is my first EV, and therefore I am hoping you experienced EVers can
help me troubleshoot and isolate the problem..... Atleast the EV is home
now thanks to AAA.
Vehicle:
1985 VW Cabriolet
120 volt lead acid.... US battery US-125 ..... 20 6volt batteries
Advanced DC 9" motor
Auburn Scientific MPWC600 - water cooled controller
Elcon DC/DC converter
power brake booster
Problem:
As mentioned above, after backing vehicle off of flatbed trailer and parking
for about 45 minutes, I returned to make final 2 mile drive home, but the EV
would no longer move. I could here contactors close, and able to read a full
voltage of 126v at the B- and B+ connections of the controller. I connected
12v Aux battery to A1 and S1 on motor to verify motor would still turn which
it did. After some reading, I suspected the controller may have triggered
itself into sleep mode due to pot box or abnormal voltage sensed by
controller. I took ohm readings on 5k pot box which read 0 at one extreme,
and 5.8k at the other extreme. I did not have time to work on car
yesterday, so car sat for 24hrs with high voltage emergency disconnect
switch behind driver activated and therefore cutting the traction pack from
controller and motor. This morning I measured pre charge voltage at
controller on B- and B+ on controller which showed 0 volts, so I closed the
emergency disconnect, and turned key switch to on, and motor would turn
while car was in neutral. I decided to drive the car and drove uphill
(steep) 30 feet in my driveway. Since car was able to pull the hill, I
coasted to bottom of hill and turned onto public street. As I accelerated
more, the motor would cutout until I released accelerator pedal and then
accelerate again, each time cutting out the motor after only slight
acceleration. After maybe 5 or 6 attempts to gain speed, the controller and
motor became completely un responsive again. Tried to zero out the
precharge voltage and start over, but was unable to wake up controller. I
am not certain if there is a reset procedure for the controller that I
should be following...... after problem occurs and I activate manual
disconnect switch, I still read 1.5 to 2 volts at B- /B+. The only
difference I have found between Santa Cruz readings and Los Angeles readings
is that when the traction pack is connected but the key switch is off I am
now reading approximately 74.5volts, and in Santa Cruz when everything
functioned normally, it would read approximately 81.5 volts. When key
switch is turned on, it reads the full traction pack voltage of 126.4 volts
both in LA and Santa Cruz. I notice as I type this that the difference in
pre charge voltage is approximately 6 volts which may indicate a loose
connection on 1 6v battery?????
Please help.... and thanks in advance! Feel free to call :)
Cheers,
Scott
