Help 3: Inspection of Electrical Connectors
INSPECTION OF ELECTRICAL CONNECTORSEach time you disconnect a connector, inspect it thoroughly to determine that it is in good condition. Focus on the circuit being checked.
Dirt and corrosion are the biggest problems in connectors, causing voltage drop, open circuits, or other improper operation. Water and dirt in a connector can allow voltage to "leak" into other circuits, leading to problems during damp/wet weather.
� Inspect both sides of the connector for water, dirt or physical damage such as corrosion and pin push-outs. Pay attention to female connectors for spread cavities.
NOTE: Use caution when testing wires to avoid damage to connectors.
� Ensure that the connector is properly wired by verifying the wire color in each cavity against the appropriate pinout illustration below. Correct any miswired connectors.
Clean, repair, or replace the connector as necessary for proper vehicle operation.
