Question about 2004 Jeep Grand Cherokee
1995 Jeep Grand Cherokee 5.1 enginge.
Check engine light came on, noticed that battery indicator showed no charging happening. Usually displays about 14, was under 9. Out of town unable to get into a shop so bought a new alternator on dealership recommendation. "Faulty" alternator would charge, then drop, charge, drop, the whole way home. Made it home, put new alternator in and bam, no charge. Needle drops all the way down when jeep is shut off but only goes up to just under 9 when running. Took that alternator out, traded it for another new one and same thing. Got mad, went back and got original alternator and put back in. Same thing. No charging yet but have become an expert at putting the blasted things in and out. Can't find a loose ground but it might be a possibility. In Minnesota and cold temperature is making things very difficult.
Thanks for any suggestions.
Find a friend with a heated garage that you can use first off, then locate the short that may be causing all this. Unless you have a bad battery? If its more than 3 years old, replace it. Batterys are cheap. WALMART has em under 89 bucks for most vehicles.

Hello and welcome to FixYa!
If the battery light is on, I strongly suggest that you have
the battery charged. It can be an indication of a weak battery or a faulty
alternator. If the battery light still on after charging then the problem will
surely be on the alternator itself. If that's the case the alternator should be
replaced to resolve the problem.
If the battery won't hold charge even on a new alternator
then the problem will be on the battery itself. It surely is in the end of it's
service life and replacement will be necessary.
You may try to reset it to by removing the positive battery
connector, letting it sit for at least 5mins. then reconnect it again. This
will reset the system and can get the battery light off.
Hope this helps and thank you for using FixYa! Have a good one!
