(3) Electrical connectors of the cigarette type.
(a)
You must tighten all electrical connectors of the cigarrette-type (found at the end of intermediate and high tension leads) until the connector flange touches.
(b)
Approximately 140-160 pound-inches (15.818-18.078 Newton meters) of torque is necessary.
