STANDARD TROUBLESHOOTING PRACTICES
Be sure master power is off before connecting or
disconnecting any electrical cable or harness unless
Anytime a connector is disconnected it should be
checked for cleanliness and broken, bent, or pushed
in pins. If you find missing or damaged pins, notify
When instructed to make a measurement to chassis
ground, ensure you make solid contact to metal
surface, free of paint, grease and dirt. Connector
backshells (not the coupling ring) and braided wire
ground straps are reliable chassis connections.
If testing for an intermittent condition, flex the
harness and test for a reading that varies above or
below the limits specified in test block.
Continuity is defined as a 0 to 5 ohms reading on a
continuity or short circuit indication when the circuit
resistance is actually greater than 5 ohms. Do not
use a buzzer or light without verifying the actual
The new cables and harnesses are covered by heat
shrink tube so the circuit (CKT) numbers cannot be
seen. Cables and harnesses are labeled with part
number and the connector ends are labeled with all
CKT numbers at that specific connector.
