Starter Motor - Feed Circuit Test

1. Make sure the battery is fully charged. Carry out a battery load test. Refer to «BATTERY, MOUNTING AND CABLES»(ref-569582) .
2. Connect a remote starter switch between the starter solenoid "S" terminal and the battery positive (+) terminal.
3. Connect the Fluke 77-IV Digital Multimeter positive lead to the battery positive (+) post. Connect the negative lead to the starter solenoid "M" terminal.
4. Engage the remote starter switch. Read and record the voltage. The voltage reading should be 0.5 volt or less.
5. If the voltage reading is 0.5 volt or less, go to the «STARTER MOTOR-GROUND CIRCUIT»(ref-569607-S34079543002013072700000) - component test.
6. If the voltage reading is greater than 0.5 volt, this indicates excessive resistance in the connections, the positive battery cable or in the starter solenoid. Move the Fluke 77-IV Digital Multimeter negative lead to the starter solenoid "B" terminal and repeat the test. If the voltage reading at the "B" terminal is lower than 0.5 volt, the concern is either in the connections at the starter solenoid or in the solenoid contacts.
7. Remove the cables from solenoid "B" "S" and "M" terminals. Clean the cables and connections and reinstall the cables to the correct terminals. Repeat Steps 3 through 6 . If the voltage drop reading is still greater than 0.5 volt when checked at the "M" terminal or less than 0.5 volt when checked at the "B" terminal, the concern is in the solenoid contacts. INSTALL a new starter motor. REFER to «STARTER MOTOR - 1.6L GTDI»(ref-569607-S07569985962013072700000) or «STARTER MOTOR - 2.0L GTDI»(ref-569607-S15799749212013072700000) or «STARTER MOTOR - 2.5L»(ref-569607-S24143822182013072700000) .
8. If the voltage reading taken at the solenoid "B" terminal is still greater than 0.5 volt after cleaning the cables and connections at the solenoid, the concern is either in the positive (+) battery cable connection or in the positive battery cable itself.
9. Clean the positive (+) battery cable connection. If this does not solve the problem, install a new positive battery cable, Refer to «BATTERY, MOUNTING AND CABLES»(ref-569582) .

Starter Motor - Ground Circuit Test

A slow cranking condition can be caused by resistance in the ground or return portion of the cranking circuit. Check the voltage drop in the ground circuit as follows

1. Connect a remote starter switch between the starter solenoid "S" terminal and the battery positive (+) terminal.
2. Connect the Fluke 77-IV Digital Multimeter positive lead to the starter motor housing (the connection must be clean and free of rust or grease). Connect the negative lead to the negative (-) battery terminal.
3. Engage the remote starter switch and crank the engine. Read and record the voltage reading. The reading should be 0.5 volt or less.
4. If the voltage drop is greater than 0.5 volt, clean the negative cable connections at the battery, the body ground connections and the starter ground connection. Retest.
5. If the voltage drop is greater than 0.5 volt, install a new cable, Refer to «BATTERY, MOUNTING AND CABLES»(ref-569582) . If the voltage reading is less than 0.5 volt and the engine still cranks slowly, install a new starter motor, Refer to «STARTER MOTOR - 1.6L GTDI»(ref-569607-S07569985962013072700000) or «STARTER MOTOR - 2.0L GTDI»(ref-569607-S15799749212013072700000) or «STARTER MOTOR - 2.5L»(ref-569607-S24143822182013072700000) .

Starter Motor Drive Gear and Flywheel Ring Gear Inspection

1. Remove the starter motor. Refer to «STARTER MOTOR - 1.6L GTDI»(ref-569607-S07569985962013072700000) or «STARTER MOTOR - 2.0L GTDI»(ref-569607-S15799749212013072700000) or «STARTER MOTOR - 2.5L»(ref-569607-S24143822182013072700000) .
2. Check the wear patterns on the starter drive gear and the flywheel or flexplate ring gear. If the wear pattern is normal, install the starter motor. Refer to «STARTER MOTOR - 1.6L GTDI»(ref-569607-S07569985962013072700000) or «STARTER MOTOR - 2.0L GTDI»(ref-569607-S15799749212013072700000) or «STARTER MOTOR - 2.5L»(ref-569607-S24143822182013072700000) . Visual check.
3. If the starter drive gear and the flywheel or flexplate ring gear are not fully meshing and the gears are scored or damaged, install a new starter motor. Refer to «STARTER MOTOR - 1.6L GTDI»(ref-569607-S07569985962013072700000) or «STARTER MOTOR - 2.0L GTDI»(ref-569607-S15799749212013072700000) or «STARTER MOTOR - 2.5L»(ref-569607-S24143822182013072700000) . If necessary, install a new flywheel or flexplate. Refer to «ENGINE - 1.6L GTDI»(ref-569555) , «ENGINE - 2.0L GTDI»(ref-569556) , or «ENGINE - 2.5L»(ref-569568) .
