Hello all! I am a small independent dealer in VA. I specialize in Wranglers. I have sold a lot of Jeeps and of course have owned several and love them!
I now have a Jeep that has me very puzzled! This is a 2004 Rubicon. It is a 5 speed and has small lift. It only has 54,xxx miles on it. It WILL NOT hold a charge. The battery will last for about 2 day and then is as dead as a stick!! Again, I have been selling Jeeps for about 15 years. This one has me stumped. I have had several techs look at this with me. No one can figure it out. Here is what I have done so far.....
Took meter to battery and removed every fuse one at a time looking for a spike. Did the same for every relay. Replaced alternator. Replace battery twice with new battery. Took battery out of another jeep in stock and swapped, the battery performed well in the other Jeep. Replaced AIC. Swapped starter to another Jeep.
NOTHING WORKED!! Please help guys! I am considering a new Engine Computer (PCM/ECM/ECU) from All Computer Resource inc. If this is the next step, has anyone installed a new PCM?
Thanks in advance for your help!
