I have an 00 grand cherokee. Lately it's been giving me a lot of problems! It's been having issues starting and then one day I was driving it and all my lights starting going crazy as well as my gauges. My ABS and brake light came on. I pulled over, turned it off, let it sit and started it back up. No more ABS or brake light. When I went to start it back again, it wouldn't start and heard a bunch of clicking noises. My jeep wouldn't even turn over, the gauges just sat there partying back and forth. When I pushed on the brake, it started right up.
I took my car to have the battery tested and the alternator, they said the alternator was bad. Got a new one, few days later, the problem came back. Now when I drive, the ABS and brake light both come on but when I turn it off, it goes away. Basically, it comes and goes. I had to get it jumped yesterday and for a while it wouldn't stay on by itself. Any ideas on what's going on with my jeep?
Corrosion and/or loose battery connection. Ongoing problem for many of us.
Remove battery connections, use a wire brush or light grit sand paper to remove the corrosion from both the battery posts and the cable ends - eb sure to get down to bare metal. Buy larger replacement bolts (drill out the existing lugs so they fit) and then tighten the terminals to the battery "gorilla tight". OEM cable bolts only allow chimpanzee tight before breaking.
Your Jeep will soon be pissing excellence all over the place again.
If the problem persists, its the battery.

another quick easy fix, use a set of vise grips to pinch the terminal loops tighter. kinda into an egg shape, then you have to tap them onto the terminals, and everything has been running much smoother since then
Make sure ya'll are also cleaning the grounds really well, not just the battery connections but the ones that go to the block and chassis as well. I would reccomend installing with dielectric grease to seal out farther corrosion.

I had a problem with my battery that would cause my vic to reset and my abs and brake lights to come on once every couple of days. When I was looking at the battery connections I noticed that one of my terminals coming out of the batt was cocked to the side. I replaced my batt and the problems went away.
