3. Disconnect wires from the (+M) and (–M) terminals of the key switch.
4. Place the red (+) probe on the (+M) terminal and the black (–) probe on the (–M) terminal. With the key
switch OFF, the reading should be continuity. With the key switch ON, the reading should be no conti-
nuity. If either reading is incorrect, replace the key switch
(Figure 11-37, Page 11-35 or Figure 11-38,
Page 11-35)
.
5. Connect wires to the key switch. Make sure wires are connected correctly and are tight. If they are not,
rewire or tighten as necessary.
