Okay so about a month ago, I was driving home from work, and stopped by to get ice cream. Turned my Jeep off, it wouldn’t turn back on, acted like a dying battery. I thought it needed gas because my gas gauge also doesn’t work, I had a spare gallon in my trunk. Put it in and the Jeep started but a weepy start. I figured I should just drive home at this point, did that. On the way home the lights started dimming. The battery gauge dropped. It was a Saturday so mechanics would be closed, my dad took a look at it and said it’s the alternator. Got one from a local junkyard and it didn’t work. Got one from Autozone and it didn’t work. He then said it has to be the battery, went to Walmart replaced that too. Nothing.
The following week I take it to a mechanic and he says it’s the alternator. We replace that. Nothing, then he taps on the computer with a screw driver and says it’s the computer. Order one from Flagship which takes two weeks before I get my hands on it, replace it, the Jeep started and the batter gauge rose to 14v and seemed normal. I left it running for about 5 minutes and turned it off and back on and then the battery gauge started to drop and it seemed like it was still broken. I take it to another mechanic and he says it’s the battery terminals. I replace those. Nothing. Same thing. I then drive it back home frustrated and ready to just junk this out already.
My friend comes over and he starts playing around with the PCM wiring harness and it the battery gauges start going up and down. He is convinced that the problem is within my wiring harness. Could this be true?
Could I get a whole new engine wiring harness rather than looking for a bad wire?
