-
The circuit is not shorted to voltage or the condition that originally caused the short may not be present at this time. Continue to measure the
resistance and wiggle the wire harness to check for an intermittent short. NOTE: By disconnecting the wire harness connectors you may have
eliminated the source of the voltage causing the short. Use the wiring application as a guide, check to see if there are any battery circuits
in the same wire harness as the circuit you are testing. It is necessary to check for a short to those circuits using an Ohm meter. See:
Troubleshooting Tests/Check For A Short Between Multiple Circuits Perform the Check for a Short Between Multiple Circuits
diagnostic procedure.
-
Use the wiring application as a guide to trace the circuits and look for any in-line connectors where the short could occur intermittently.
-
Look for any chafed, pierced, pinched, or partially broken wires.
-
Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal contact in the related component and wire
harness connectors.
-
Perform any Technical Service Bulletins (TSBs) that may apply.
Check A Ground Circuit For An Open Using A 12-Volt Test Light
CHECK A GROUND CIRCUIT FOR AN OPEN USING A 12-VOLT TEST LIGHT
1. Turn the ignition off.
2. Disconnect the wire harness connectors of the components that contain the ground circuit suspected as containing excessive resistance.
NOTE: Check connectors - Clean/repair as necessary.
3. At this time leave all in-line connectors connected.
NOTE: Before inspecting any circuits, first test the 12-volt test light. Connect the 12-volt test light to battery ground or to any other known
good ground. Touch the lead of the test light to Battery +. If the test light is good, it should illuminate brightly.
4. With all the component wire harness connectors disconnected, connect the 12-volt test light to Battery +.
5. Use the test light lead to lightly probe the ground circuit in the harness connector.
Does the test light illuminate brightly?
Yes
-
The suspected ground circuit is not open or the condition that originally caused the open or excessive resistance is not present at this time. Another
way to check for an open would be to use an Ohm meter and measure the resistance of the ground circuit. While continuing to measure the
resistance of the circuit, wiggle the wire harness and connectors to check for an intermittent open or poor connection.
-
Use the wiring application as a guide to trace the circuits and look for any in-line connectors where the open could occur intermittently.
-
Look for any chafed, pierced, pinched, or partially broken wires.
-
Look for broken, bent, pushed out or corroded terminals. Verify that there is good pin to terminal contact in the related wire harness connectors.
-
Perform any Technical Service Bulletins (TSBs) that may apply.
No
-
Repair the open in the circuit between the two wire harness connectors. Use the wiring application as a guide to trace the circuit and look for any
in-line connectors where the short could occur.
