Important: Use the J 35616-A Connector Test Adapter Kit whenever a diagnostic procedure requires inspection or probing a terminal. Use the adapter in order to ensure that no damage to the terminal may occur. This will also ensure that the contact tension is sufficient. If the contact tension seems incorrect, refer to Checking Terminal Contact.

Important: In order to avoid misdiagnosis, ensure that you zero the J 39200 before taking measurements.
