Just got this truck in the shop today and need some assistant.
Truck has no high speed. Truck has a 30 volt battery, (first one I've seen). Accelerator checks good, has nice sweep on meter, 1A bypass switch checks good but only has 5 volts going through it?? 1A coil has same resistance as fwd & rev. If I give the 1A coil a ground from the battery in will engerize. Need to know where the ground for the coil comes from. Need a wiring diagram if any one has one. Not sure what SCR system it has but I belive the SCR is before the GE EV1 system. Data tag says truck was made by Yale - Eaton - Towne
