I just purchased a 1995 Solectria from an ex EV1 owner here in Southern California...so now I feel officially part of the club! Anyway, the vehicle under full...
I have experienced the same problem in my 1992 force. An electrical engineer colleague said that it seemed like a hunting problem (control system feedback...
At first blush I would check the batteries. If they are nearing the end of their life it might act like that. Check the pack voltage under no load and under...
... Might this service manual help me with my 1992 Solectria? It's dead now. Almost surely a sensor problem. I haven't found it yet. The inverter just never...
Gary, The situation improves when I am in the econommy made. However, going up a steep driveway, the car doesn't make it. The previous owner stated that it...
The speed sensor problems really only show up under a load. It sounds to me like the speed sensor board needs a little adjustment. If you have a manual, this...
I have been kicking this around a while and I have some thoughts. I know this sounds a bit strange, but see if this makes any sense. The motor speed sensor...
I think this is the cause of bearing failures in the Force. I never had it cause a problem with the speed sensor though. The tolerance is not that close. I...
This is Chris Reeves' former car! It seems the shuddering problem is back. I tried hard acceleration in reverse and it does the same shuddering. I am still...
The pot box is on the firewall inside the engine compartment, if you're looking at the firewall from the front of the car it will be on the extreme upper...
Well, since we are comparing drive system problems. On one of my 1997 Solectria's when it is "cold" and it goes into regen, there is a relatively loud...
Yes, my first '95 Solectria squealed a bit on heavy regen, but I never noticed a temperature variation. The second one is not as noticeable a squeal, but it...
... Small world (or maybe not, there aren't that many Forces). ... I would try checking out the motor speed sensor. I wonder if has just gone out of...
Hello Dave I have a 1997 and it does have a loud screeching sound in regen. The lower the batteries are the less it screeches. As a test I went down a hill...
Will Becketts mentioned bearing failures in the Force. My 1992 Force (belt drive to a home-made differential) seems to be getting noisier, especially on...
For $5 you can by a replacement pot for the pot box. Here is my experience, I hope it works for you. I disconnected the power and opened up the pot box after...
Dave: Yes, I have experienced the same loud screeching noise in regen. I was wondering if it is a bearing. If it gets too much worse I plan to get a tranny...
The bearing problem I had was in the gear box but I replaced all the bearings including the motor. I expect the motor bearing could be a problem for you. The...
My 99 Force makes this noise when regenerating in the first couple of miles after a full charge. My battery monitor shows that some batteries go way...
Yup, the motor controller will not allow regen to exceed a set voltage. The squeal and vibration are the controller alternating between regen and no-regen. If...
Solectria has told me that they need to do the repairs on the motor bearings specifically because of the gear box. They say putting the motor/gearbox together...
Don, Right now it's my mom who drives the car down in Palo Alto at her house since I live in San Francisco and don't have parking. So I don't want to burden...
Yes but then I expect the Bob Schneeveiss might be considered more than just a good mechanic. It is all standard stuff for someone that has done this kind of...
I have had a medium pitch rrr-rrr sound in my drive motor for well over a year. It makes the noise when driving at low speeds (below 35) and when regening....
I don't believe it would be bearings in this case. You should hear the problem with regen on or off if it were bearings. Also, I don't think it would be a...
If not the bearings then what in the regen mechanism might cause this sound to occur. Like I said it occurs during regen and during lower speed driving until...
It would be nice to hear the sound. A lot of funny things can happen in the speed sensor it not adjusted correctly. Maybe others have some suggestions. -...
... could it be a side-effect of the over-voltage limit? These controllers limit the regen voltage. What if its oscillating when you are over-voltage. As the...
I just purchased Deka 8G34R (60Ahr) batteries for my EV conversion. Unfortunately the technical literature is sparse in determining the proper charger profile....
