New Step by Step Map For alternator repair

If practically nothing assessments bad, then It can be most likely that the voltage regulator is lousy. Regrettably there is not any good way to check the regulator once the alternator is disassembled.

Put the ohmmeter on the two slip rings about the alternator shaft (exactly where the brushes Get hold of). There really should be Practically no resistance. Set one lead about the slip ring and a person over the alternator shaft. There need to be infinite resistance.

Truly the only other areas that might be poor would be the rotor and stator. These can idiot your ohmmeter take a look at, since the resistance in between the 3 wires of your stator and the two slip rings to the rotor is quite near zero.
