DESCRIPTION
Starter is a brush type, series wound electric motor with an overrunning clutch. Field frame is enclosed by commutator end frame and drive bushing and carries pole shoes and field coils. A spline armature shaft drive end carries drive assembly. Armature shaft is supported at both ends by sintered bronze bushings.
STARTER LOAD (LOCK) TEST
With starter on test bench, lock starter drive pinion. Voltmeter and ammeter readings should be within specification.
STARTER NO LOAD TEST
With starter on test bench, operate starter and check ammeter, voltage, and RPM. Readings should be within specification.
STARTER DOES NOT CRANK ENGINE
- Ensure battery is fully charged. Make sure electrical and ground connections are clean and tight. With ignition switch in crank position, measure voltage at spade terminal of starter solenoid. If reading is at least 8 volts (9.5 on Fox), go to step 3).
- If not, measure voltage at ignition switch. If reading is at least 8 (9.5 on Fox) volts, check wiring between ignition switch and starter solenoid. If not, replace ignition switch.
- Measure voltage at field (starter) terminal of starter solenoid. If reading is at least 8 volts, repair or replace starter. If not, replace starter solenoid.
Note. On vehicles with automatic transmissions, also check park/neutral switch.
STARTER TURNS TOO SLOWLY
Ensure engine crankcase is filled with recommended viscosity oil. Check charging system to ensure battery is fully charged. Make sure electrical and ground connections are clean and tight. If starter still turns slowly, repair or replace starter.
REMOVAL & INSTALLATION
Note. Only difficult starter removal and installation procedures are covered in this article.
Removal & Installation (Fox)
Disconnect negative battery cable. Support engine/transmission assembly with Support Beam (VW 10-222 ). Remove engine mount bolts, nut, and clamp screw (next to exhaust manifold flange). Remove engine mount. Disconnect wiring and remove starter. To install, reverse removal procedure.
