About 6 inches forward of the battery, a red wire (one of 4 wires in a harness) is burnt and throwing smoke/spark. I noticed a patch of soot under my seat during regular checking/cleaning which lead me to the red wire where the insulation has been burt through and wire was exposed. I wrapped the spot with electrical tape. I'm a noob and not sure what this wire is for or how to resolve the issue. Any help would be greatly appreciated. The system is stock for what I can observe.
