If you have a car where the battery dies after leaving it, try plugging a solar charger on the dashboard into the cigarette lighter. This has kept me out of trouble for quite a while. Note that the cigarette lighter must be the type that is still connected when the ignition is off. Nick B

I had an alternator that drained the battery .It was fine for years but I had a small Holley carb fire which was put out with the help of someones disposable fire extinglisher .It made a big mess .The alt leaked a rather unstable 100mA .I cleaned and stripped and cleaned and stripped and cleaned and got it down to 10mA .Put it back in my 1965 Stude ...

That sounds like a loose connection at a specific wire. Car alternators have a control output to tell the instrument cluster or the ecu that the alternator is running and generating power. It there is voltage on that wire, the battery lamp is off and vice versa. In allmost all cars it's as simple as this. Most likely the wire on that terminal wasn't ...

I do know somebody who left an older car parked for a month outside and the alternator seized, but that could happen to any number of accessories and wouldn't be specific to the alternator. Also, if the battery has discharged from lack of use, it will cause a higher load on the alternator while it's charging it back up. This is probably more of an issue ...

If you have a volt meter that you can connect to the battery you will be able to check the alternator. Before starting the engine, check the battery voltage, it will probably be a little over 12v. Now start the engine and turn on your headlights to draw some power. If the alternator is working, the battery voltage should now be between 13.8 and 14.4 ...

In an alternator there are two major components; the stator and the rotor. The rotor has a coil wound on it. By applying a current to that coil a magnetic field is formed and then spinning the rotor electricity is excited in the stator. Because the rotor needs to spin while mainaining electrical contact for the coil slip rings are used. There are ...

The only thing I can think of as a response is Copper. Copper is used in alternators to house a spinning magnet. This creates electricity to power your car. The only problem I can foresee is how easily copper is affected by weather. Copper will oxidize and create a green coat. This oxidation can impede its ability to harness/(assist in creation) ...

Had the same problem, no start but had headlights, wipers, horn, etc. starter and battery were good. long story short, remove the ground strap/wire between the engine and body and scrape the paint off down to bare metal on the body and make SURE all connections are clean. reinstall and problems solved. Gotta have a GOOD ground between vehicle body and ...

I put a AGM battery in my audi a4 1999 , and the computer got confused enough to throw up annoying symbols on the dash , like bulb out errors and the like , so i changed back to excide premium 90AH , I recon the cars computer just could't figure out what had changed ,with the AGM being able to be recharged 5 times faster than the standard battery , but no ...

Are you sure it's the alternator that's whining? Check your connections the Field plug on the alternator and the alternator to battery cable. There should never be zero volts coming out of the alternator. It will always be battery voltage or charging voltage. Test voltage at the battery. then at the alternator if the alternator show charging voltage there ...

I had a '91 Suburban with which the alternator was making noises like you are suggesting. This Suburban was new enough to have a serpentine belt, like yours. I let it go too long and the alternator seized up. When this happened the force was enough to stop the engine dead in its tracks. Yes, the serpentine belt has that much grip ... I was quite surprised. ...

Cars commonly multiplex their electrical systems. This means that multiple things are fed from the same fuse. The best way to identify what is on the fuse is to check the wiring diagrams. Once all the possible sources from the fuse have been identified the fault can be systematically narrowed down. First look at components that come on and off, this is the ...
