Charging Problem


96 Ford Probe, 83,000 miles 2.0L - For about 3 months I have been experiencing problems with my charging system. The Serp-Belt that is on my crank pulley, water pump, and altenator pully will squeal like crazy, but heres the kicker. If the RPMs are high the voltmeter in my dash reads normal. But when you put any load on the altenator such as: stereo, headlights, heat, or defroster the gauge falls like a brick. I'll be driving on the highway with no problems, no matter how much power electronics I turn on in the car there will be absolutely no problems, but when I reach a red light and begin to slow down, the voltmeter takes a dive. I replaced the belt (because it broke off) the battery, the altenator, cleaned all the grounds, changed the battery terminols, everything I could possible imagine. I even made sure that the pulleys were dead straight with each other. I tested the battery when the car was shut off and the volts read 12V DC. When the car is running, and the voltmeter reads normal, it reads 14.5V DC which is normal.I've taken to multiple mechanics and left with all of them stumped. So if you could solve this mystery I will be both extremely greatful and very impressed. Thanks Guys

Do you
