TROUBLESHOOTING
TESTING (ON VEHICLE)
CIRCUIT TESTING
1. Turn ignition switch to START position, depress clutch and ensure starter operates. If starter does not
operate, use voltmeter to check voltage at "S" terminal when clutch is depressed and ignition is turned to
START position. See Fig. 1
.
2. If voltage is less than 8 volts, check starter interlock switch and ignition switch to starter wiring circuit for
short to ground. If voltage is greater than 8 volts and starter is inoperative, starter has an internal fault.
Repair or replace as required. NOTE: For information on B2200 and Protege models with automatic transmissions,
see STARTERS - GEAR REDUCTION article.
NOTE: See TROUBLE SHOOTING - BASIC PROCEDURES article in the GENERAL
INFORMATION section.
NOTE: Before testing, ensure battery is fully charged, battery cables and terminals are
clean and tight and engine grounds are good.
