1989 Ford Probe LX mileage: 108,000. I have a question regarding my car's charging system. It has a history of charging system problems. The system completely failed about three years ago, I ended up replacing the battery, alternator and power distributor. Everything was fine until about a year ago when the system quit again, I had it checked and it was the alternator again. I replaced it myself and it was fine again until now. However, now it has some occasional problems with overcharging. I have not had any problems with light bulbs or fuses burning out. However, a couple times a week the voltmeter will read slightly above normal. There were a few squeaks in the belt, after which I tightened it and although the noise is mostly gone, the same problem with overcharging still exists. I have also noticed that the car seems to lose some power when it is doing this, but the acceleration will pick up again once the voltmeter is reading a normal charge. Do you have any ideas on what might be causing this?

Your intermittent charging problem may be caused by poor ground connections somewhere in the system. Replace the belt for the alternator. Belts squeak due to slippage and must be replaced.
