A friend of mine, Lars, has an electric Geo Metro. He was having a battery over heating problem while charging, and I read that 1 bad battery can make the whole pack over heat during charging. We tested the charge of all th ebatteries and found one that was 6v (he has 8v batteries) and we disconected it from the pack. His overheating problem went away. Cool.
Now he has another problem where he has full battery voltage but nothing happens when he steps on the throttle. We'll try to look at it tomorrow and see if we can figure it out. The gas pedal feels right, but no response for the motor, Any one have any ideas or know of a good way to start trouble shooting an electric car? He didn't build his, so we have some detective work to do.
