Motor Ground Circuit
NOTE: A slow cranking condition can also be caused by high resistance in the ground circuit.1. Disconnect the wiring from the fuel shutoff solenoid.
2. Connect the Digital Volt-Ohmmeter positive lead to the starter motor housing.
3. Connect the Digital Volt-Ohmmeter negative lead to the battery negative (-) terminal.
4. Connect a remote starter switch between the starter solenoid S-terminal and the positive battery terminal post.
5. Press the remote starter switch and record the voltage reading.
6. The voltage reading should be 0.2 volt or less. If the voltage reading is higher, remove and clean the negative cable connections at the battery, starter motor and the body.
7. Retest the system. If readings are still higher than 0.2 volt, test each individual negative cable.
