With a Test Lamp

WARNING: This page is about a different car, the 2002 Pontiac Montana, 2002 Oldsmobile Silhouette, and 2002 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.

Important: 

Only use the test lamp procedure on low impedance power and ground circuits.

  1. Remove the power feed (i.e. fuse, control module) from the suspect circuit.
  2. Disconnect the load.
  3. Connect 1 lead of the test lamp to 1 end of the circuit to be tested.
  4. Connect the other lead of the test lamp to battery positive voltage.
  5. Connect the other end of the circuit to ground.
  6. If the test lamp illuminates (full intensity), then the circuit has good continuity.
