Important: Use the J 35616 Connector Test Adapter Kit whenever a diagnostic procedure requires testing or probing a terminal. Using the adapter will ensure that no damage to the terminal will occur, as well as giving an idea of whether contact tension is sufficient. If contact tension seems incorrect, refer to Checking Terminal Contact in General Electrical Diagnosis Procedures for specifics. | ||||
