TEST PROCEDURE 4 – KEY SWITCH (STARTER CIRCUIT)
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 1-2.
3. Remove the center dash assembly. See Key Switch Removal, Section 12, Page 12-14.
4. Ensure that the connector is connected correctly and is tight. If not, repair or replace as necessary.
5. Insert the key and turn the key to ON. Place the red (+) probe of the multimeter on the (B) terminal and
the black (–) probe on the (L) terminal of the key switch. The reading should be continuity. If the reading
is incorrect, replace the key switch (Figure 11-28, Page 11-25). See Key Switch Removal, Section 12,
Page 12-14.
6. With the key still in the ON position, place the red (+) probe of the multimeter on the (B) terminal and the
black (–) probe on the (S) terminal of the key switch. The reading should show no continuity. If the reading
is incorrect, replace the key switch. See Key Switch Removal, Section 12, Page 12-14. If the reading
is correct, leave the probes connected and proceed to the next step.
7. Insert the key and hold the key in the START position. The reading should be continuity. If the reading is
incorrect, replace the key switch (Figure 11-29, Page 11-25). With the red (+) probe of the multimeter on
the (B) terminal and the black (–) probe on the (L) terminal of the key switch, the reading should be con-
tinuity. If either reading is incorrect, replace the key switch. See Key Switch Removal, Section 12,
Page 12-14.
