Faulty electrical connections or wiring may cause most
intermittents. Inspect for the following conditions:
• | Poor mating of connector halves |
• | Terminals not fully seated in the connector body (backed out) |
• | Dirt or corrosion on the terminals |
| Ensure that the terminals are clean and free of any foreign material
that may impede proper terminal contact. |
• | Damaged connector body - exposing the terminals to moisture and
dirt |
• | Improper terminal orientation with the component or mating connector |
• | Improperly formed or damaged terminals |
| Carefully inspect all connector terminals in problem circuits in order
to ensure good contact tension. Use a corresponding mating terminal in order
to inspect for proper tension. |
• | Use the J 35616
Connector Test Adapter Kit whenever a diagnostic procedure requests
inspecting or probing a terminal. Using the adapter will ensure that no damage
to the terminal will occur, and will indicate whether contact tension is
sufficient. |
• | Poor terminal to wire connection |
| This includes the following conditions: |
- | Crimping over wire insulation rather than the wire itself |
- | Corrosion in the wire to terminal contact area |
• | Wire insulation that is rubbed through |
| This causes an intermittent short as the bare area touches other wiring
or parts of the vehicle. |
• | Wiring broken inside the insulation |
| This condition may cause a continuity inspect to show a good circuit.
If only 1 or 2 strands of a multi-strand type wire are intact,
resistance may be too high. |
In order to avoid any of the above conditions when making wiring or
terminal repairs, always follow the instructions for wiring and terminal repair
