Testing For Intermittent & Poor Connections: Notes

Most intermittent conditions are caused by faulty electrical connections or wiring. Inspect for the following items:

• Wiring that is broken inside the insulation
• A poor connection between the male and female terminal at a connector
• A poor terminal to wire connection--Some conditions which fall under this description are poor crimps, poor solder joints, crimping over the wire insulation rather than the wire itself and corrosion in the wire to terminal contact area, etc.
• Wire insulation that is rubbed through - This causes an intermittent short as the bare area touches other wiring or parts of the vehicle.
