Using an ohmmeter, exam the diodes, both regulator diodes (triode in Delcotron) and rectifier diodes. A diode is really a "A method valve" for electricity, so each diode need to demonstrate some resistance studying about the meter A technique, and no reading, or infinite resistance the other way. A bad diode will both have infinite resistance both of those ways, or will conduct some existing (demonstrate a looking at over the meter) both techniques.
