Default Re: 80 cc 36v not moving

In the early "stock" carts ( I find that many carts that old have been converted in some manner ) like yours there was either 4 or 5 micro switches inside a white box with red ends mounted on top of frame rail under drivers seat. Connected to pedal and inside the white box is a plastic board afair cut in various lengths that touches micro's in sequence that turns on solenoids to change speed.
The tracing order is as follows
#1 power to key switch
#2 power from key switch to micro on back of F&R switch
#3 power from micro on F&R AFTER either placed in F or R to 4 or 5 micro's inside white box with red ends
#4 micro in white box to first solenoid ( master power feed ) that feeds through brass bar to other solenoids
#5 micro's in white box to the other solenoids to give changing speed by going through solenoids to large coil resistors in sequence
Hope this helps you check for problem?
