Intermitent charging system
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.

Re: Intermitent charging system
I would replace the alt ... I believe there is a voltage regulator within the alt that only charges the battery once it gets to a certain level (it doesn't need to charge the battery all the time).
Also, if you battery is nearing 5yrs it would probably be worth swapping that out too ...

Re: Intermitent charging system
Ditto on the alternator. The brushes are worn out and brush springs are weak.
