One way to help isolate the short is to disconnect any in-line connectors that the circuit being checked runs through and check for the short again.
If the short goes away, the short is on the other side of the in-line connector.
No
-
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
voltage 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 wire harness connectors.
-
Perform any Technical Service Bulletins (TSBs) that may apply.
4. CHECKING FOR A SHORT TO VOLTAGE USING A 12-VOLT TEST LIGHT
1. Turn the ignition off.
2. Disconnect the wire harness connectors of all components that contain the circuits that are suspected as being shorted.
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. Connect the 12-volt test light to a known good ground circuit.
5. Use the lead of the test light and carefully probe the circuit you suspect has a short.
WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not
wear loose clothing. Failure to follow these instructions may result in possible serious or fatal injury.
6. First, check with the ignition off , next with the ignition on, and lastly while cranking the engine.
Does the test light illuminate brightly?
Yes
