Intermittent And Poor Connections

Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly, check the following items:

• Connectors are fully seated

• Spread terminals, or terminal push out

• Terminals in the wiring assembly are fully seated into the connector/component and locked into position

• Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem

• Damaged connector/component casing exposing the item to dirt or moisture

• Wire insulation that has rubbed through causing a short to ground

• Some or all of the wiring strands broken inside of the insulation

• Wiring broken inside of the insulation
