Stator Coil Resistance
Disconnect the alternator leads connectorthe stator coil resistance Measure an ohmmeter between the alternator leadsConnect
Stator Coil Resistance Standard: 0.3 or less
If the meter does not read as specified, replace the alternator statorIf the coil has normal resistance, but the voltage inspect showed the alternator to be defective; then the rotor magnets have probably weakened, and the rotor must be replaced
