Gidday guys, was out on the farm last night with the big spots on. The 40 drove fine untill the head lights started flickering at low rpms. I turned the truck off with everything still working well but now it wont start?. I have no electrics at all, the car is totally dead ie no headlights, starter or anything else electrical. The battery is still good as the spots are connected directly to it and they still work. I think the 400watts of spots may have shat something

. Could it be the fuse on the coil? Any help would be greatly appreciated as driving the nissan to work sucks compared to my cruiser. Cheers
