alternator repair Secrets

Utilizing an ohmmeter, examination the diodes, each regulator diodes (triode in Delcotron) and rectifier diodes. A diode is a "A technique valve" for energy, so Just about every diode should exhibit some resistance studying over the meter A technique, and no studying, or infinite resistance one other way. A nasty diode will possibly have infinite resistance both equally methods, or will perform some existing (show a reading within the meter) both of those means.

Some voltage regulators utilizes this for a reference alternator repair to regulate the alternator output. Typically the brushes (and the rotor area) are driven via a separate set of diodes. Delco alternators have such a set of diodes, named a TRIODE ASSEMBLY: It can be three diodes in a single
