[QUOTE="DOWNS, post: 441964, member: 21038"] As Gila mentioned. Start with your grounds, especially battery to engine and chassis grounds, your battery cables can look good on the outside but will be a tube of solid corrosion on the inside, if you don't know the last time the cables were replaced go ahead and do it. THere are good kits out there or you can take the old ones to the parts store and build some from what they have there, the last set of battery cables I did at the parts store ran me 60 dollars for the cables and hardware and myself at the counter guy built them with their tools on the counter before I left. Bad grounds=high resistance=lots of heat build up. They can also cause lots of weird electrical gremlins on these Jeeps as lots the sensors depend on a 5V reference signal. [/QUOTE]
