So a little back story before I get to my questions. I was driving the jeep last night and stopped for gas. When I tried to get going again it wouldn't turn over. I was able to bump start it (by myself, in an HEB parking lot...
) and get it back home, but it wasn't able to start from the battery anymore. I figured it was the battery, so I went to autozone and picked up a new one. When I got that it, the voltage meter was only saying it was at about 11-12 volts when I was driving, so when I returned the core battery they check my alternator and they said that it was only putting out about 12v, when it should really be putting out about 13-14v. They recommended I replace the alternator too.
I unfortunately am just getting started in the world of do-it-yourself repairs, and I was wondering if anyone could weigh in on whether that would be the right approach, or if there is anything else I should check before I just start throwing money at it and replacing entire components.
BTW: It's an 84 CJ7 inline 6 4.2
