I have 1998 jeep cherokee 4x4 4.0L. I've tested the alternater, battery, starter, (they all tested good) and replaced the pick up coil, but the battery is still not charging. It's backfiring, the dash light goes haywire and the speedometer and rev counter lose their readings. I had to run a hot wire from alternater to battery using a toggle switch to be able to drive and keep charge. I have tried to reset the computer by disconnecting the battery, but still have the same issues. It is also burning at least twice as much fuel since the electrical problems have occurred. any suggestions will be appeciated, thanks.
I had an issue with these symptoms on my Chrysler minivan. The problem turned out to be a bad battery. It seemed to be ok, but was making intermittent contact because the negative stud was loose, and eventually broke off in my hand. Once I put a new battery in, everything went back to normal and the van has been running great since.
