Jabin - basically what is happening is that you are experiencing a large, constant current draw, not a Voltage/ current spike.
I would most like suspect a missing ground or a wire that has rubbed through creating a partial hard short. Look for melted wires, those tiny wires heat up pretty quick and will melt the insulation. You should be able to trace it from that. Repair or add grounds where necessary.

Let me know if you need more info. I will be heading for teh Silver State Classic tomorrow morning so it might take a bit for me to reply..
