Employing an ohmmeter, examination the diodes, both equally regulator diodes (triode in Delcotron) and rectifier diodes. A diode is usually a "A technique valve" for electrical power, so each diode should present some resistance reading within the meter one way, and no reading through, or infinite resistance another way. A nasty diode will either have infinite resistance both ways, or will conduct some present-day (display a looking at within the meter) equally means.
