Electrical Problem with my car?
My car is currently down and out. It's having some sort of electrical problem. So far the alternator, the serpentine belt, and a wire that somehow acts as a fuse have all been replaced. What I have been told is that the alternator is giving off too much power. I've been through three garages and no one seems to be able to find the problem. My car is a '94 Buick Century. It's in great shape overall but I've already thrown 400 dollars at it trying to fix it. I don't want to throw more money at it and hope it works. Any ideas?
Okay, it is making my car go haywire. It won't always respond to my foot hitting the gas the way it should and all of the needles and lights on the dash board go crazy- flying back and forth all over the place.

Too much power is a regulator issue... which on your car is inside the alternator... have it checked again.

you are not saying what the suppposed overcharging is doing to your car.
However.
The wire that acts as a fuse is a Fuselink. If you have a short in certain area or to much amperage is leaking thru it,,it will melt and disconnect the circuit,,,,thae same as afuse in a house would.
The alternator has an internal voltage regulator to limit the amount of voltage that it recharges the battery to no more than about 14 1/2 or 15 volts.In normal circumstances.
But you are saying there is something abnormal but not explaining what it is.
As a side note. overcharging a battery will ruin it. You may need to replace it.

it sounds to me like its overcharging, probably the voltage regulator isnt working like it should. take the alternator off and have it checked for output. if the regulator is working right, it shouldnt let the alternator overcharge the battery.

not sure if that alternator has a built in regulator...if so there is a small hole in the back that you can adjust the output...this need to be done with a voltmeter connected.... if you have an external regulator it's bad!
