Circuit/System Testing
NOTE:
You must perform the Circuit/System Verification before proceeding with Circuit/System Testing.
- Ignition OFF, disconnect the X1 harness connector at the G13 Generator.
- Verify the charge warning lamp does not turn ON when ignition ON.
- If the charge warning lamp illuminates
- Ignition OFF, disconnect the harness connector at the P16 Instrument Cluster.
- Test for infinite resistance between the control circuit and ground.
- If less than infinite resistance, repair the short to ground on the circuit.
- If infinite resistance, replace the P16 Instrument Cluster.
- Go to next step: If the charge warning lamp does not illuminate
- Install a 3 A fused jumper wire between the control circuit terminal 1 and ground.
- Verify the charge warning lamp turns ON when ignition ON.
- If the charge warning lamp does not illuminate
- Ignition OFF, remove the jumper wire and disconnect the harness connector at the P16 Instrument Cluster, ignition ON.
- Test for less than 1 V between the control circuit and ground.
- If 1 V or greater, repair the short to voltage on the circuit.
- Go to next step: If less than 1 V
- Ignition OFF.
- Test for less than 2 Ω in the control circuit end to end.
- If 2 Ω or greater, repair open/high resistance in the circuit.
- If less than 2 Ω, replace the P16 Instrument Cluster.
- Go to next step: If the charge warning lamp illuminates
- Replace the G13 Generator
