Lulling into work today my jeep shut off. All the electrical was off and I coasted into a space. My winch still worked, so I figured the battery had a charge. I went inside and got changed for work, I looked outside and the headlights were back on. I went downstairs, turned the key, the dash lights went on, I tried to start the jeep and everything shut off again. I got a jump pack from work, hooked it up and everything started fine. I put the jeep in a garage bay and let it run for an hour. I checked back later and it started right up.

Recent history: I had a dead battery and replaced it a month ago. Prior to that I had corroded wires to the terminal that I cleaned. I have cube lights and a winch that have been on the jeep for 18 months with no problems. When the battery died the first time my dad had been using the winch for an afternoon to pull shrubs. At the time I assumed he had drained down the battery over the course of the day.

I'm thinking I have a problem with the alternator, has anyone experienced something like this or have suggestions?

What I don't get is, if the battery had enough charge to run the winch and the winch used the same connection as the rest of the jeep, why did one get power and the other didn't? And then when I added a jump pack to the same terminals, it then worked. It doesn't seem to me that some components would work and some wouldn't.

Bad connection at the battery terminal, thanks for all the help and suggestions!
