Turn and hold the key switch in the START position. The reading should indicate continuity. If the reading does not
indicate continuity, replace the key switch
. 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 not indicate
continuity. If either reading is not correct, replace the key switch.
See Key Switch Installation on page 12-7.

See General Warning on page 1-2.
1.
Turn the key switch OFF. Place the Forward/Reverse handle in NEUTRAL and set the park brake. Chock
the wheels.
2.
Disconnect the 16-gauge green wire (w110) from the starter solenoid coil to prevent the vehicle from
unintentionally starting
See following WARNING.
WARNING
• Failure to disconnect the wire from the solenoid coil could result in an unexpected engine start
when performing this test.
3.
Set the multimeter to 20 VDC.
4.
Place the probes to measure the voltage between the 16-gauge green wire (w110) terminal and the frame ground.
5.
Monitor the multimeter. The reading should indicate 0 volts with the key in the OFF and ON positions. The
reading should indicate approximately 12 VDC when the key is in the START position.
