1997 3.2 2WD 299,000 miles original alternator
3 times in the last month when I start up first thing in the morning dash warning lights are lit up and the electrical system is not charging. AC doesn't work and windows operate very slowly. A simple rev of the engine has resolved the problem. However, the belt is very tight (and I mean very) and there is no indication of it slipping.
This morning, a rev didn't solve the problem. I only work a few miles from home and my mechanic is also very close so I just figured to head that direction. About 1/4 mile later charging kicked in and everything worked just fine.
I hate Intermittent electrical problems

Where to start.
