Testing for Intermittent and Poor Connections
Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items:
^
Duplicate intermittent fault conditions by wiggling the harness, disconnecting and reconnecting connectors, pulling on the mechanical connection of
a connector, pulling on the harness or wire in order to identify a separation/break inside the insulation.
^
Test for electrical intermittent opens, high resistances, short to ground and short to voltage on electrical circuits.
^
Wiring that is broken inside the insulation.
