Ignition OFF.
Test for less than 2 Ω between the G13 Generator housing and battery negative terminal.
- If 2 Ω or greater
  Repair the open/high resistance in the circuit.
- If less than 2 Ω
Verify a test lamp illuminates between the G13 Generator B+ circuit terminal 1 X2 and ground.
- If the test lamp does not illuminate and the circuit fuse is good
1. Remove the test lamp and disconnect the B+ cable at the G13 Generator.
2. Test for less than 2 Ω in the B+ circuit end to end.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.
• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
