Question about Cars & Trucks
Same model in petrol voltage regulator setting 14 volts diesel model 13 volts. Why??
Because the amp output of the alternator is very high.
The internal regulator may have a popped diode.

SOURCE: Alternator or Voltage regulator
if you can carefully put a metal wrench on the rotating pulley of the alternator and felt a magnetism attracting the metal wrench, then your alternator is charging. if there is no magnetism, then the alternator is not charging...
another test is to measure the voltage on the small wires that went in to the alternator that says "F" for field, it should measure battery voltage...that is the voltage from the regulator..that means your regulator is working...but the altrntor is not..
without that battery voltage, then the regulator is he culprit...
pls be carefull...
hope i was able to solve ur problem..
pls rate me.. tnx, drcool..

Voltage regulator is going bad. Have alternator tested or go ahead and have it replaced. Also this would be a good time to have the battery tested. Usually an alternator that is over charging will "cook" the battery causing it to not charge, not hold a charge, to losing the gel/electrolyte solution due to boil out.

On the terminal maked"l" you need to put switched power from the ignition[ the problem], will go away.If this is not an option then you can get an alternator repair shop to put a self exciting regulater and it will kick in with a quick rev of the engine,no wireing required
