I was able to get by with a little less. Tech 2 scanner used from ebay was $1100.00, I? charged the batteries individually using 2 chargers that were $100 or so for the 2. I have dropped the pack several times on the garage floor using substantial jack stands and a heavy duty...

Jay, ? ??? You need a few items for this project...a tech 2 scanner (aprox. $3,000). a fairly substantial regulated dc power supply (aprox. $750), a set of good batteries (the shipping is almost as much as the batteries if you can find good ones), some way to get about 36 inch...

Hello all, I just subscribed to this list yesterday because I found the S-10 EV that Michael is selling on E-bay. (He mentioned the list, so I assume he's also a subscriber.) I live in Atlanta (85mi south of Eljay) and am looking for a EV to make short (3mi round trips) commut...

I had a somewhat similar problem. In my case it was due to a bad Hall sensor in the PIM. Everything was actually working OK but a sensor was sending a bad signal. So the truck would shut down because it thought the voltage was out of phase. Unfortunately, the hall sensor is no...

I had this problem on my truck after driving a bit too hard. I believe what you are seeing is a set of failing IGBT's, in that their leakage current has grown to large. It means that the gate driver circuitry is unable to shut them off sufficiently. In my case the problem got...
