Important: 

   • The battery must be in a charged state in order to avoid misdiagnosis.
   • The J 35616-A Connector Test Adapter Kit must be used whenever a diagnostic procedure requires checking 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.
