How are the wires connected to the alternator?

• Four wires connect the alternator to the rest of the charging system. • B is the alternator output wire that supplies current to the battery. • IG is the ignition input that turns on the alternator/regulator assembly. • S is used by the regulator to monitor charging voltage at the battery.

What causes an alternator to go over 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.

What should I do if my alternator is not working?
