BALL 4B9880 - Caterpillar

Use this procedure under the following situation:Use the following steps to help determine if the connector is the cause of the problem. If a problem is found in the electrical connector, repair the connector and verify that the problem has been corrected.The following background information is related to this procedure:Many of the operational procedures and the diagnostic code procedures in this troubleshooting guide will instruct you to check a specific electrical connector. The engines use a variety of Deutsch and AMP connectors. Intermittent electrical problems are often caused by poor connections. Always check for an active diagnostic code before breaking any connections. Also, always check for an active diagnostic code after the connector is reconnected in order to verify that the problem disappears. Simply disconnecting the connectors and then reconnecting the connectors can temporarily solve a problem. If this occurs, likely causes are loose terminals, bent terminals, improperly crimped terminals, corrosion, or harness routing.
