1987 gas ezgo marathon

[woodrahini2]

Solenoid clicks when gas pedal is pushed, but that's as far as it goes. Won't turn over so we can check spark, etc... Was told the wires may be crossed between the gear switch and the starter... When in neutral, there is small spark at the pos terminal when hooking up the battery. When it's in forward or reverse, there's bigger spark upon connection as well as a little smoke... As if something may well be hooked up backwards???
