I have restored my 79 3 wheel EZGO Marathon golf cart. New electrical parts include new micro switch and solenoid as well as batteries. When I put everything back together everything works great except when I put it in reverse it goes forward and in forward it goes in reverse. I didn't unhook wires on controller or accelerator. I did disconnect motor wires. I reversed wires on solenoid and got same result. Same on micro switch. I traced all the wires to make sure they matched my drawing - they do. I reversed the series wiring on the batteries with the same result. I thought about reversing motor wires but can't find a wiring diagram that tells which wires control motor direction. Any suggestions?
