My jeep check engine light came on.
My volt meter went to 0.1. I changed the alternator and it worked for about 10 seconds and it went out. I installed another one and it did the same thing!!!
What is the issue?

Your question is relatively vague, however there are a few things that could be at issue.
You could have a short circuit in your system that is draining the battery, which could also overload the alternator, causing it to fail. Since most of the circuits in a car are behind fuses, a short causing the problem you describe would have to be before the power distribution module (fuse panel), which means it's most likely something directly connected to the battery check:
- Connection from battery to starter
- Connection from battery to fuse panel
- Connection from battery to alternator
- Check the Alternator
It could also be a bad battery. If the battery was allowed to discharge to low, it won't take a charge anymore.
