Starter No-Load Test
WARNING: This page does not describe the selected car, but rather 26 other vehicles, including the 1999 Pontiac Sunfire, 1999 Pontiac Grand Prix, 1999 Pontiac Grand Am, 1999 Pontiac Firebird, and 1999 Pontiac Bonneville. However, it is still accessible from the selected car via links, so may be relevant.
- Secure starter in vise. Turn carbon pile off and open switch. Connect test equipment to starter as illustrated. See Fig 1. Turn switch on and adjust carbon pile until voltage reads as specified. See STARTER NO-LOAD TEST SPECIFICATIONS table. Check ammeter reading and pinion speed on RPM indicator. Turn off carbon pile and open switch. Compare RPM and amperage readings with specification.
CAUTION:
DO NOT apply more voltage than specified. Excessive voltage may cause armature to throw windings due to excessive speed.
- If amperage and RPM readings are as specified, starter motor is okay. If readings are not as specified, replace starter assembly. See STARTER under REMOVAL & INSTALLATION.
