Ground Wire Getting Hot. What causes this!?
 
So week or so ago i posted this thread.

http://www.wranglerforum.com/f5/fog-...lp-190077.html

I did strip it all .. the housing on the ground wire is good .. it was weird when i first stripped it down and checked the connections and plugged it back in it worked just fine. So i unplugged taped them up real nice and plugged them back in and didnt come back on.. the ground wire from the light gets real hot. It comes from that small connection between the light and the plug to the wiring.

my question is
Do ground wires/fog lights just go bad and need to be replaced?
Is there a way to fix this myself?

A wire that is getting hot simply has too small of a gauge (diameter) for the application (or possibly the circuit is shorted or miswired). A wire providing a ground to one side of a driving light, for example, has to be the same size as the hot wire providing power to the light. The same amount of current entering a component like a light bulb is exactly the same amount of current (amperes) leaving it.

got you , sooo i did notice that some of the copperwiring within the ground wire were broke and not connected. That could cause it??

Sorry not savvy with wiring.

Yep if there are broken strands in the wiring, those strands can't help carry the amperage drawn by the light which increases the load on the remaining strands that are forced to carry the added load. Like slackers in a boat crew not pulling their fair share makes the others have to work harder. Sounds like the wire needs to be replaced.

just adding to this, make sure the location where your ground goes is clean. Sometimes if the electrical current cant make proper contact, i.e. paint or rust in the way, the wire will get hot. Just take some sand paper and clean off the area it bolts to if your still having issues.. Good luck
