- Remove the capacitor from the alternator.
- Touch terminal (2) to housing (1) in order to discharge the capacitor.Note: Discharge the capacitor after each measurement.
- Connect the multimeter leads across terminal (2) and housing (1) of the capacitor.
- Measure the resistance.Expected Result: The resistance is low for a short period of time. The resistance stabilizes above 100000 ohms.
OK – The resistance stabilizes above 100000 ohms. The capacitor is normal. Repeat Step 2. STOP.
NOT OK – The resistance does NOT stabilize above 100000 ohms. The capacitor has failed. Replace the capacitor. STOP.
