Continuity Check

Measure resistance between connector terminals at both ends of the circuit being checked (between "A-1" and "C-1" in figure). If no continuity is indicated (infinity or over limit), that means that the circuit is open between terminals "A-1" and "C-1".

Disconnect the connector included in the circuit (connector-B in figure) and measure resistance between terminals "A-1" and "B-1".
If no continuity is indicated, that means that the circuit is open between terminals "A-1" and "B-1". If continuity is indicated, there is an open circuit between terminals "B-1" and "C-1" or an abnormality in connector-B.
