[QUOTE="DOWNS, post: 440314, member: 21038"] Battery and ground cables can look fine externally but be a tube of corrosion inside the insulation. The exposed wires wick water/moisture/crud into the insulation and overtime it just becomes a tube of powder. With enough conductivity to run most of the Jeep but when tasked with carrying the hundreds of amps of starter load simply have too much resistance. This would explain why you're seeing 9v at the starter when you try to crank. And why trying to jump it did no good. I'm willing to bet that cleaning the ground points and new cables will fix you up. I took my cables down to Orileys and myself and one of the younger counter guys built a new set of cables right on the table at the store with a lug crimper they had and terminals off the shelf. I think total cost was 60 dollars all said and done. Ive got the Jeepcables on the XJ and it really is a top notch kit. [/QUOTE]
