Employing an ohmmeter, take a look at the diodes, equally regulator diodes (triode in Delcotron) and rectifier diodes. A diode is really a "A method valve" for energy, so Every diode should demonstrate some resistance looking through within the meter A technique, and no examining, or infinite resistance one other way. A bad diode will possibly have infinite resistance both approaches, or will conduct some current (display a studying within the meter) both equally strategies.

There may be lots of good reasons for a lack of charge: alternator failure (voltage regulator, stator difficulties, slip rings worn out, etc), but make also absolutely sure your battery continue to normally takes the charge, Test the alternator belt.
