ON-VEHICLE TESTING
Note. Before testing, ensure battery is fully charged, battery cables and terminal ends are tight and clean, and engine grounds are secure.
CLUTCH START SWITCH TEST
- Switch is located above clutch pedal on bracket. Disconnect wiring harness connector from switch.
- Connect ohmmeter probes to switch terminals. Depress clutch pedal. If continuity does not exist, adjust or replace clutch start switch. If continuity exists, check circuit to starter relay for open, and check starter relay. See «STARTER RELAY TEST»(ref-60825-S01944222502001011800000) .
IGNITION SWITCH CONTINUITY TEST
| WARNING | Deactivate air bag system before performing any service operation. See AIR BAG RESTRAINT SYSTEM article in the ACCESSORIES & EQUIPMENT section. |
- Disconnect negative battery cable. Remove driver's lower instrument panel cover. Remove upper and lower steering column covers if needed. Locate ignition switch wiring harness 8-pin connector. (Scheme 1)
- With ignition switch in LOCK position, there should be no continuity between any terminals. With ignition switch in ACC position, there should be continuity between terminals No. 5 and 7. With ignition switch in ON position, there should be continuity between terminals No. 2 and 3, and between terminals No. 4, 5 and 7. With ignition switch in START position, there should be continuity between terminals No. 1, 2 and 3, and between terminals No. 4, 7 and 8. If continuity is not as specified, replace switch.
Scheme 1
STARTER RELAY TEST
- Remove starter relay, located in driver side kick panel, on top of junction block No. 1. Using ohmmeter, verify continuity between relay terminals No. 1 and 2. (Scheme 2) Continuity should not exist between terminals No. 3 and 5. If continuity is not as indicated, replace relay.
- Check relay operation by applying battery voltage through terminals No. 1 and 2. (Scheme 2) Continuity should now exist between terminals No. 3 and 5. If relay does not test as indicated, replace relay.
Scheme 2
NO-LOAD TEST
| CAUTION | DO NOT engage starter solenoid for more than 5 seconds during testing, or damage to coil winding will result. |
Note. Starter type and kilowatt (kW) rating can be found on a metal label attached to side of starter.
- Remove starter. Connect ammeter in series between starter motor terminal No. 30 (battery terminal) and a fully charged 12-volt battery. Connect battery negative to starter case ground. (Scheme 3) Connect voltmeter to battery to observe voltage draw readings.
- Connect remote starter or jumper wire to terminal No. 30 and to terminal No. 50 to engage starter. Starter drive pinion gear should extend quickly and spin smoothly. Verify starter amperage draw and battery voltage draw to be within specifications. See «NO-LOAD TEST SPECIFICATIONS»(ref-60825-S13747794592001011800000) table. Replace starter if not within specification.
Scheme 3
| Application | Maximum Amps @ Volts | RPM |
|---|---|---|
| 1.4 kW | 90 (11.5) | 3000 |
NO-LOAD TEST SPECIFICATIONS
Drive Pinion Return Test
Disconnect jumper wire from negative battery terminal to starter housing. see scheme 8 Pinion gear should now retract. If it does not retract, replace solenoid.
TROUBLE SHOOTING
Note. See TROUBLE SHOOTING - BASIC PROCEDURES article in the GENERAL INFORMATION section.
- If a no-start condition exists and battery is known to be good, connect test light or voltmeter between starter solenoid terminal No. 50 and ground. (Scheme 3)
- Turn ignition switch to START position. If test light or voltmeter does not indicate voltage, check main fusible links and large ampere main fuses in engine compartment relay box. If fusible links and fuses are okay, see «IGNITION SWITCH CONTINUITY TEST»(ref-60825-S36985993462001011800000) and/or «STARTER RELAY TEST»(ref-60825-S01944222502001011800000) under ON-VEHICLE TESTING.
