Alternator and Regulator Circuit Test
Alternator and Regulator Circuit Test
1. Be sure the battery is sufficiently charged and in good condition.
2. Raise the hoist to full height.
3. Hook up the ammeter, 0 - 400 A, to the starter sub-harness.
4. Lower the hoist.
5. Hook up the voltmeter, 0 - 20 V (accurate within 0.1 V), to T101.
6. Start the engine. Hold the engine at 3,000 rpm with no load (in Park or Neutral) until the radiator fan comes on then let it idle.
7. Raise the engine speed to 2,000 rpm, and hold it there.
8. Turn the headlights (high beam) on, and measure voltage at the under-hood fuse/relay box terminal.
Is the voltage between 13.9 and 15.1 V?
YES - Go to step 9.
NO - Repair or replace the alternator.
9. Read the amperage at 13.5 V.
NOTE: Adjust the voltage by turning the blower motor, rear window defogger, brake lights, etc. ON.
Is the amperage 60 A or more?
YES - Alternator/regulator operation is OK.
NO - Repair or replace the alternator.
