No Voltage to Starter Solenoid
To determine if no voltage to the starter solenoid is causing the engine to crank slowly or not crank, perform the following steps:
- Visually check the battery cables for exposed or cut wires.
- If the battery cables are exposed or cut, repair as necessary (refer to "15.2.1 Repair of Cable Using the Splice Method" ) and proceed with step 2 of inspection.
- If the battery cables are not exposed or cut, reuse the component and proceed with step 2 of inspection.
- Visually check the solenoid cables for exposed or cut wires.
- If the solenoid cables are exposed or cut, repair as necessary. Refer to "15.2.1 Repair of Cable Using the Splice Method" .
- If the solenoid cables are not exposed or cut, check the starting circuit connections. Refer to "15.3 Starting Circuit Connections Loose or Corroded" .
Repair of Cable Using the Splice Method
Perform the following steps to repair cable(s) using the splice method:
- To repair straight leads using the splice method:
- Locate broken wire.
- Remove insulation as required; be sure exposed wire is clean and not corroded.
- Slide a sleeve of shrink wrap on the wire long enough to cover the splice and overlap the wire insulation.
- To repair leads using solder is an optional method:
- You must use rosin core solder.
- Check the exposed wire before the splice is crimped in its connector. The exposed wire must be clean before splice is crimped.
- Use a suitable electronic soldering iron to heat the wires. Apply the solder to the heated wire (not the soldering iron) allowing sufficient solder flow into the splice joint.
- Pull on connector to ensure crimping and soldering integrity.
- Verify repairs. Refer to "15.2.2 Test Engine with Repaired Cables" .
Test Engine with Repaired Cables
Perform the following to determine if the repaired battery cables resolved the fault:
- Attempt to start and run the engine.
- If the engine failed to start and run, check for loose or corroded starting circuit connections. Refer to "15.3 Starting Circuit Connections Loose or Corroded" .
- If the engine started and ran, no further troubleshooting is required.
