How do you fix an alternator that is not charging?
Check the large power cable to the alternator and the fuse, usually, a large 40-60 amp fuse near the battery. Check the ground cable between the engine and the body. Check the serpentine belt and make sure the alternator is spinning with the engine. Check the small power supply wire and the charging light wire.
Why is my alternator not working on my Capri?
The regulator inside maybe failing, one of the diodes may be failing, the brushes inside are not functioning correctly due to age and wear, bearings are shot, or the pulley attached becomes unattached and the belt has problems turning. On a 1991-94 Mercury Capri, good quality alternators, either Bosch or Mitsubishi, cost anywhere from $130-200.
What does it mean when your alternator stops charging the battery?
Indicator Light On. Usually, the first sign that your charging system is in trouble is a “battery,” “ALT,” or “CHARGE” warning light illuminating on your instrument panel while driving.

Why does my alternator get higher than base voltage?
You should get 0.5 to 2 volts higher than base voltage. If you are getting more than 2 volts above base voltage, most likely your alternator is over-charging the battery or the battery is faulty. Other potential problems are a faulty voltage regulator or a problem in the charging system wiring.

Can a bad car battery cause an alternator to not charge?
In theory a car can run only with the alternator charge, but this can cause heavy voltage spikes and other strange symptoms so this means that a bad car battery can cause an alternator to not charge also. Cars are increasingly coming with modern electronics.

What happens when the alternator of a car is dead?
The alternator and the car’s battery work hand in hand. A good battery should give you service for the next five years before its lifespan ends. If your battery is dead, then it will not give power to the car’s alternator. The alternator normally lasts longer than the battery.
