DETAIL
Intermittent And Poor Connections
Most intermittent problems are caused by faulty electrical connections or wiring. A sticking relay or solenoid can also be a problem. When diagnosing
intermittent problems, check the following items:
1.
Poor mating of connector halves.
2.
Terminals not fully seated in the connector body (terminal backed out).
3.
Dirt or corrosion on the terminals. The terminals must be clean and free of any foreign material.
4.
Improperly formed or damaged terminals.
All connector terminals in problem circuits should be checked carefully to ensure good contact tension (Figure 1). Use a corresponding mating
terminal to check for proper tension.
5.
Poor terminal to wire connection.
Examples of this are poor crimps, poor solder joints, crimping over wire insulation rather than the wire itself and corrosion in the wire to terminal
contact area (Figure 1).
6.
Wire insulation which is rubbed through, Causing an intermittent short as the exposed area touches other wiring or parts of the vehicle.
7.
Wiring that is broken inside the insulation.
8.
Corroded wiring inside the insulation.
Both the conductor and insulator must be free of any corrosive damage to ensure good conductivity.
ACTION REQUIRED
