Re: No spark from coil! how can i bypass? help
sounds like you have a short in the 12v circuit to the coil if the jumper wire got really hot when trying to jump voltage to coil try checking voltage at auto shut down relay should be 2 wires with 12v at the relay if not try checking fuses or fuse links

Re: No spark from coil! how can i bypass? help
one relay will have a green/black tracer and red 14gauge wires make sure the red wire has battery voltage key on and if yes when the relay is energized the red 14ga and green/black wire are connected together these are the 2 bigger wires on the relay and make sure the bigger red wire has battery voltage with key on
