Test Procedure 17 – Key Switch (Engine Kill Circuit), Continued:
5. Place the red (+) probe on the (M) terminal and the black (–) probe on the (G) terminal. With the key
switch OFF, the reading should be continuity. With the key switch turned ON, the reading should be no
continuity. If either reading is incorrect, replace the key switch (Figure 11-52, Page 11-40).
6. Reconnect the key switch to the wire harness. Ensure that the connector is connected correctly and is
tight. If it is not, repair or replace as necessary.

TEST PROCEDURE 18 – ENGINE KILL WIRE
See General Warning, Section 1, Page 1-1.
1. Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in NEUTRAL. Chock
the wheels.
2. Disconnect the battery cables as instructed (Figure 11-1, Page 11-5). See WARNING "To avoid unin-
tentionally starting..." in General Warning, Section 1, Page 1-1.
3. Disconnect white/black wire bullet connector located at the engine RPM limiter (Figure 11-41,
Page 11-33).
4. Connect red (+) probe of multimeter to the male bullet terminal on the white/black wire and connect the
black (–) probe to the vehicle frame.
5. With the Forward/Reverse handle in the NEUTRAL position, turn the key switch to the ON position and
note the multimeter reading. Turn the key and hold it in the START position while noting the multimeter
reading. There should be no continuity when the key switch is in the ON or START position. If there is con-
tinuity, check for worn insulation on the white/black wire that is allowing the wire to ground to the frame.
