I have a 2000 XJ 4.0 with 150k miles. The electrical accessories I have include upgraded H4 headlights with harness, (2) 130 watt KC lights wired in with high beams, stock fog lights, and heated seats.
My current battery is an Autozone Duralast Gold with 800 CCA, it is about 1 year old. This replaced my Optima yellow top after it failed.
I have recently added Jeepers and Creepers battery cables, 5-90's alternator cable with 200A ANL fuse, and a 150 amp alternator. The alt is a stock sized case rebuilt to handle 150A.
Ever since this winter hit, my Jeep turns over slow. I thought it might be the starter, but the Jeep only cranks slow on a cold start. If I drive somewhere, then park it for an hour or two and come back it will crank right up. If I'm driving and turn my high beams on (with the KCs) everything is fine. If I turn the high beams (and KCs) on while sitting idle at a stop sign, the lights will dim and the volt gauge will drop to 12 volts. Turn the high beams off and everything goes back to normal at idle. If my electric fan comes on with just the head lights on, the battery gauge will dip to 12 volts again.
I never noticed this with my Optima battery and stock battery cables. Is this an electrical system problem or just a crappy battery? I tested the battery with a load tester and it tested OK, but that was also after driving it for a bit. Battery terminals have been replaced with brass terminals.
I'm stumped. Any help is greatly appreciated.
