TROUBLE SHOOTING

Note. See TROUBLE SHOOTING article in GENERAL INFORMATION.

ON-VEHICLE TESTING

Note. On models with anti-theft system, obtain code number and deactivate audio anti-theft system before disconnecting battery.

CIRCUIT TEST

Ensure battery is fully charged, battery cables and terminals are clean and tight, and engine grounds are okay. If starter does not operate, measure voltage at starter "S" terminal (Black/Red wire) with ignition switch in START position (ensure clutch is depressed on M/T or gear selector in Park on A/T). If voltage is greater than 8 volts and vehicle does not crank, repair or replace starter as required. If voltage is 8 volts or less, check ignition switch, park/neutral switch (A/T), starter interlock (clutch start) switch (M/T) and wiring.

NO-LOAD TEST

Remove starter. Connect fully-charged 12-volt battery, voltmeter and ammeter to starter. (Scheme 5) Using remote starter wires or jumper, engage solenoid. Starter should spin smoothly. Compare readings with specifications. See NO-LOAD TEST SPECIFICATIONS table. If voltage is less than specified or amperage is more than specified, repair or replace starter as necessary.
