electrical problems are often caused by poor connections. Use the following checks as a reference for inspecting connectors.
Check the connection of the connectors.
Ensure that the locking rings are properly locked.
Ensure that locking clips are used on Sure Seal connectors.
Ensure that the center of the connector is tight.
Ensure that the connector pins and sockets align properly.
Check the wires at the connector.
Ensure that the wires enter the back of the connector straight.
Ensure that each wire is properly crimped into the proper connector contact.
Ensure that each connector contact is properly locked into the connector contact. When the connector contact is locked properly, the contact (wire) cannot be pulled out of the connector body without excessive force.
Check each wire for nicks or signs of abrasion in the insulation.
Check for moisture at the connector.
Check for damaged connector seals or lost connector seals.
Check for missing or loose wire hole plugs.
Check for wires that do not enter the connector properly.
If the wires enter the connector at an angle, there may not be a good seal between the connector and the wire insulation.
Moisture can enter the connector through the wire insulation.
Check for dirty contacts or corroded contacts.
Clean contacts with a cotton swab or a soft brush and denatured alcohol only.
Check each pin and each socket.
Check each contact of the connector for a snug fit by using a new pin and socket. The new contact should stay connected if the connector is held with the contacts that are facing down.
