On the small diode bridging the two terminals on a 48 volt system solenoid, does it matter which end of the diode goes to which terminal? If so, what would the effect be if it was installed backwards? Thanks!
Yes, to say the least. As I posted on the 26th, I accidently arced/sparked the two main terminals on the motor, and the solendoid diode heated up and smoked. Cart then became inop. Before I replace the controller, which may or may not be fried, I went ahead and replaced the solendoid/diode, and cart now goes only in reverse when switch is in either F or R. Wonder if a backwards diode would cause that condition. A local tech said that if the cart moves in ANY direction, the controller is probably okay, and that the burned diode stopped the volage spike from getting to the controller. If the diode IS installed backwards, I suppose turning it around and seeing what happens is the next step....thanks.
