Pack Rat: My 1992 Solectria 120 volt charger's fan is directly wired to the incoming 120 volts so it is always on.? My charger has a grill over the fan that...
Hello, Turns out the charger has a temp sensor. The fan kicked on by itself after a while. Don't know what kind of charger it is yet. I connected the DC-DC...
Philip and Stephen, Would each of you be willing to update the list on how well your respective Valence packs are working? Could you speak to how well the ...
I haven't been using the pack in the Sunrise, because I sold the car so i can't comment about the production models which is what you would be most interested...
The Valence pack appears to be working fine although with more droop on highway driving than I expected. The droop however seems to recover very quickly....
Thankyou both of you. Stephen how many cycles and miles have the engineering prototypes in the Force endured? Mark ... car so i can't comment about the...
I've driven the car 18,000 miles on the batteries, but I am not sure of the number of cycles. I don't think the cycle life has been the issue. My problem has...
I opened up the controller (AMC-325) to discover some fried MOSFETs. Has anyone been confronted with this, and what to do? Is the only repair facility...
Bill: A few other questions: 0)?? Any idea about what caused the controller to fail? 1)? Does anyone have a schematic of the AMC 325? 2)? Are the MOSFETs the...
Thanks Gary. The drive failed while driving with a 180 amp fuse failure. The pc board is intact and one or 2 MOSFETS on one bank of MOSFETS show thermal...
Bill: Some times when MOSFETs fail, they become a short.? A short across the power supply (150+ volts) will cause the 180 amp fuse to blow.? It may also have...
Hi Bill, 98% of the time fets fail shorted. What can blow the fuse is that the upper and lower fets for one of the phases either gets stuck on due to being...
I removed the heat sink amd discovered 1 of 3 pc boards that shorted to a bolt head. Clearly a defect. These boards communicate thru a flat cable to the mP. ...
Are there any arcing marks on the bolt head or the heat sink? Mike PS microprocessor is abbreviated uP :) ... to a bolt head. Clearly a defect. These boards...
Thanks for the tip. The heat sink came off cleanly- no arcing here. I took another look burn marks on a circuit board. I was mistaken. The pcb is opposite some...
My 1998 Force recently started making a sort of scrape-scrape or tap-tap noise with the rate of the noise proportional to the speed of the car and no...
Bill could you clarify the info on shorting to a bolt head. I wasn't sure if you retracted that in your last post. Do you think the bolt caused the problem or...
Hello Mike. No, I looked at the gap where an arc would have had to jump, and it was too far (1/4"). So upon further examination, I noticed that the arc was...
Thanks for clarifying that for me. I thought that was what you were saying but wanted to make sure. The Force drive motor- If you google "induction motors" you...
I posted some photos on the "Photo" section called "BRUSA Controller challenges". Bill S ... information ... uses a ... phase ... 3 ... some ... wasn't ... ...
From the pics you posted it looks like the bad fet just spewed itself all over rather than there being a capacitor being shorted. Is the fet right across from...
The fet connects to a pcb, the same one to which the cap connects, and they are adjacent. I will dis-assemble the unit further this weekend. Bill S ... itself ...
All, I've successfully repaired my amp hour meter using David Patterson's excellent information. I thought I would post a summary since this seems to be a...
Joshua: Glad you were successful with your repair and thanks for posting the excellent summary for others to use, although the original post is getting a...
Thank you for the summary. When I first bought my Force the AH meter fuse was blown and I replaced it and haven't had a problem for two years (and it came from...
I hate it when someone has a problem and suddenly others have similar problems. I think these cars are secretly communicating with each other. Yes, I to have...
Doug: Would suggest you disconnect power to AH meter (remove 2 amp fuse) until you have time to investigate edge of AH board. When in regen and at end of...
I recently purchased a 1995 E10 and it is missing the top to the front battery box. Anyone have an extra, or know where to fine one? If not I will have to...
Sorry I don't have one. The covers on my 1994 Solectria Geo Metro are made of a black fiberglass. I just made the rear battery cover out of Lexan (poly ...
