- Disconnect capacitor lead (2) from the terminal on the back of the alternator. Remove the plastic housing from lead (2) that surrounds the clip.
- Touch lead (2) to the capacitor mounting screw (1). This discharges the capacitor.
Note: Each time this test is done, the capacitor must be discharged.
- Put the multimeter on the 20M resistance (Ohms) scale. Connect one multimeter lead to capacitor lead (2). Touch the other lead to capacitor mounting screw (2) .
