Test Procedure 7 – Solenoid, Continued:
9. With the Forward/Reverse handle still in NEUTRAL and the neutral lockout cam in the SERVICE (MAIN-
TENANCE) position, set the multimeter to 20 volts DC and place the red (+) probe on the large post that
does not have wires connected to it. Place the black (–) probe on the vehicle frame. Turn key switch to
the ON position, press accelerator pedal, and listen for solenoid click. The meter should read full battery
voltage. If the reading is incorrect, replace the solenoid
(Figure 11-18, Page 11-22)
.
10. Disconnect the 6-gauge black wire from the negative (–) post of the battery before reconnecting the wires
to the solenoid.
TEST PROCEDURE 8 – NEUTRAL LOCKOUT LIMIT SWITCH
See General Warning, Section 10, Page 10-1.
This switch is located on the Forward/Reverse switch assembly. For pedal-start vehicles, a black wire, a
green wire, and a white wire are connected to this limit switch. For key-start vehicles, a red wire and green
wire are connected to this switch.
1. Disconnect the battery cables as instructed.
See WARNING “To avoid unintentionally starting...” in
General Warning, Section 10, Page 10-1.
2. Check for proper wiring and tight connections.
3. Set the multimeter to 200 ohms. Place the red (+) probe of the multimeter on the common (COM) termi-
nal of the limit switch. Place the black (–) probe on the normally open (NO) terminal of the switch. Without
the lever pressed, the reading should be no continuity. Press the lever, and the reading should be con-
tinuity. If either reading is incorrect, replace the limit switch
(Figure 11-19, Page 11-23)
.
4. Check to be sure the lobes on the cam are pressing the neutral lockout limit switch as the Forward/
Reverse shifter is being shifted. The limit switch should make an audible click as it is pressed. If it does
not, check for wear on the cam lobes. Be sure the cam snaps fully back into place. If the cam lobes still
do not activate the limit switch, replace the cam.
