To check the alternator output voltage, do the following procedures.
Remove the regulator/rectifier and disconnect the connector [A].

Connect the hand tester to the connector as shown.
- Special Tool - Hand Tester: 57001-1394
Start the engine.
Run it at 4 000 rpm of the engine speed.
Note the voltage readings.
Alternator output voltage
Tester Range | Connections | Reading @3 000 rpm | |
Tester (+) to | Tester (-) to | ||
250 V AC | One white lead | Another white lead | 54 V or more |
★ If the output voltage shows the value in the table, the alternator operates properly and the regulator/rectifier is damaged. A much lower reading than the value in the table indicates that the alternator is defective.
Repeat the test for the other white leads.

Hand Tester [A]
Check the stator coil resistance as follows:
Turn off the ignition switch.
Connect the hand tester [A] to the connector as shown in the table.

Note the resistance readings.
Stator coil resistance
Tester Range | Connections | Reading | |
Tester (+) to | Tester (-) to | ||
x1 Ω | One white lead | Another white lead | 0.11-0.17 Ω |
★ If there is more resistance than shown in the table, or no hand tester reading (infinity), the stator has an open wire and must be replaced. Much less than this resistance means the stator is shorted, and must be replaced.
Using the highest resistance range of the hand tester, measure the resistance between each of the white leads and chassis ground.
★ Any hand tester reading less than infinity (∞) indicates a short, necessitating stator replacement.
★ If the stator coil has normal resistance, but the voltage check showed the alternator to be defective, then the rotor magnets have probably weakened, and the rotor must be replaced.
Repeat the test for the other white leads.
