2. Disconnect the connector from the device(s) to gain access and isolate the terminal for the circuit being tested.
3. Connect the positive lead of the load test tool to the positive side of the Battery.
4. Using an approved connector back probe tool, connect the negative lead of the load test tool to the ground circuit at the component harness connector (A). Note:  refer to the diagram above.
   NOTE:

   The bulb on the load test tool should be illuminated and bright if there is no resistance in the ground circuit.

   CAUTION:

   Use only approved connector back probe tools when back probing a connector so as not to cause damage to the terminals or insulation of the connector. Damage to the terminals can cause poor terminal contact or retention. Damage to the insulation can introduce corrosion due to water intrusion.

   Does the bulb light bright, as when compared to a direct Battery connection?

   Yes 

   • The circuit being tested can carry a load, check other circuits, connectors and terminals for concerns.

   No 

   • Repair the circuit, connector or terminal that has an open or excessive resistance.
   • Perform any related Recalls or Service Bulletins that may apply.
