- Connect a jumper wire from negative cable to positive side of ammeter. Connect a second jumper from minus side of ammeter to negative battery post.
- Attach one end of a third jumper wire to positive battery post. Disconnect voltage regulator plug and touch other end of jumper to white/red wire terminal on male side of regulator plug. CAUTION - Do not leave this wire connected for more than 15 seconds.
- Read ammeter and increase engine speed until ammeter reads maximum value. If value is below specifications, alternator must be repaired or replaced.
