Making use of an ohmmeter, test the diodes, both equally regulator diodes (triode in Delcotron) and rectifier diodes. A diode is usually a "A method valve" for electrical power, so each diode should really show some resistance reading through within the meter A technique, and no looking through, or infinite resistance the opposite way. A bad diode will both have infinite resistance equally means, or will perform some present (clearly show a studying over the meter) the two ways.
