I have a '93 Mark and I've come across a problem
well... let me start off the thread letting you all know that I'm not a seasoned mechanic or electrician, but I'm not afraid to get my hands dirty. My father is better with cars but is computer illiterate.
well, this all started last week when my car was broken into and the stereo was taken.. $300 later I had a window and stereo...
after the stereo was installed (by best buy) the little charging system light started showing up and the speakers were picking up noise from the electronic system any change in voltage especially when the air compressor kicks on when the unit is off or the faceplate is removed,
which led me to believe that the alternator is going out..
BUT the noise is apparent with the key turned to on/accessory without the engine running (though it isn't as loud as it is when the engine is running)..
Well, today I was searching under the hood and noticed the idler pulley had seized... I replaced that thinking that maybe had caused the problem... at first the light did go off and the noise was barely apparent, but has since returned...
I tested the alternator at about 13.5 volts at idle and the same at 3500 RPMs.. that seems fine to me..
I had a conversation over the phone with the owner of a local electical shop and he said he believes it may be a ground problem and it will run me $77 bucks an hour for him to take a look...
I can't afford to do so, but I also cant run the risk of frying my electrical system...
I've checked and cleaned the battery terminals, I have checked the ground connection... checked every damn fuse in the car and also the connections to the fuses... again I'm a car novice so I am at a loss.. I don't know much about electrical systems other than knowledge of complete circuitry, etc.
but I have no idea where to start looking for a ground problem, if i had the money i'd gladly pay the electrical shop...
