Circuit/System Testing
WARNING: This page is about a different car, the 2013 GMC Acadia, 2013 Chevrolet Traverse, and 2013 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
You must perform the Circuit/System Verification before proceeding with Circuit/System Testing.
- 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
- If 2 Ω or greater
- Verify a test lamp illuminates between the G13 Generator B+ circuit terminal A X2 and ground.
- If the test lamp does not illuminate and the circuit fuse is good
- Remove the test lamp and disconnect the B+ cable at the G13 Generator.
- Test for less than 2 Ω in the B+ circuit end to end.
- If 2 Ω or greater, repair the open/high resistance in the circuit.
- If less than 2 Ω, verify the fuse is not open and there is voltage at the fuse.
- If the test lamp does not illuminate and the circuit fuse is open
- Remove the test lamp, disconnect the battery negative cable, and disconnect the G13 Generator B+ cable.
- Test for infinite resistance between the B+ circuit and ground.
- If less than infinite resistance, repair the short to ground on the circuit.
- If infinite resistance, test or replace the G13 Generator.
- If the test lamp illuminates
- Test or replace the G13 Generator.
