It seems this electrical problem won't go away. :bawl: When my XJ sits overnight the battery drains. I went through this for months, taking it to several shops, etc. Thought I had it fixed.
I know it's not an inside lamp, engine bay light, etc that's left on. Keep in mind this is an intermittent problem. An alternator specialty shop checked out my alternator and said it's fine. They said the factory alarm had more draw than they thought was normal, so they disconnected the alarm system. I swapped the Shut Down & AC relays around in case the relay contacts were sticking.
My 4-year old Optima red top battery had gone through so many drains and jump starts that I figured it was dead. I replaced the battery with a new red top about 1.5 months ago. Everything was fine until last night when I went to move my Jeep into the driveway and the battery was totally dead.
What I'm looking at now are 1) a chaffed hot wire grounding out somewhere, 2) voltage regulator problem, 3) bad alternator, and 4) a whacked out power antenna, though the antenna started acting up after the problem began. It sometimes doesn't power up when I turn the radio on; likewise, it doesn't always power down when I shut off the radio.
Before I throw money at this, I plan to check the power antenna and computer for bad wiring. If that checks out, then I'm leaning toward replacing the alternator. I just spoke to a buddy who had an alternator act similar to my problem. The computer is very costly to replace, so that's last. Anyone have other ideas or similar experiences that might point me to something else? Thanks,
Tom
