OK, here is the deal. My son in law wanted to change all my wiring from 4 gage to 2 gage.he said he wired one line at a time, Well when I came home from work we turned on the switch and there was a pop and now nothing works. No click or life in the cart. My question is dose anyone have the wiring dirgram to a 92 marathon? and where do I start with a dead cart?
