Jeepjeff859 Posted June 9, 2015 Posted June 9, 2015 I was driving to work and randomly my jeep shut off and had no power, but the turn signals worked, some one stopped and gave me a jump and it started and I was able to finish the drive to work, as soon as I got to worked and turned it off, it had no power again, I touched the computer and it was really hot, any ideas 1986 jeep Comanche 2.5 cyl
Jeep Driver Posted June 10, 2015 Posted June 10, 2015 You'll need to go through your wiring/cables.........bad grounds are generally the culprit.
Jeepjeff859 Posted June 10, 2015 Author Posted June 10, 2015 Would really cause it to seem like the battery is completely dead, the engine won't even get a hit until the jumper cables were on for 2 min, and once it started it ran fine
Megadan Posted June 10, 2015 Posted June 10, 2015 I would agree with a bad ground or maybe a bad or loose charge wire. If the alternator tests fine, then it sounds to me like you have a draw on the battery greater than the alternator is outputting. That would explain why it needs a couple of minutes on a jump before it will kick over.
Jeepjeff859 Posted June 10, 2015 Author Posted June 10, 2015 found out the red wire from the alternator to the positive of the battery was really small and had a splice in the middle that as just tapped, it was a corroded. so that most have been not letting the alternator charge the battery enough. Went though and replaced every battery cable possible with 0 gauge wire. works fine now
Megadan Posted June 10, 2015 Posted June 10, 2015 Good stuff, looks like my educated guess wasn't too far off. Glad to hear it was something simple! Love cheap fixes like that.
