NOTE: When a switch is replaced, test the new switch to
make sure it works correctly.
1. Move ground speed control lever out of the neutral
gate.
2. Move ground speed control lever slowly back into the
neutral position while observing switch through the
dashboard. The lever should depress the switch
when in the neutral gate.
G. Test Neutral Safety Switch (Electrical)
NOTE: When a switch is replaced, test the new switch to
make sure it works properly.
NOTE: The neutral safety switch is located under the
dashboard and may be easier to test if removed. Use a
1/4” drive ratchet, a 1” extension, and 1/4” shallow sock-
et to remove the two plastite screws that secure the
switch to the dashboard.
1. Remove the wire harness plug.
2. Place the ground speed control lever in neutral
(depress the switch).
3. Set the VOM to Ohms. Touch one probe to each of
the top row terminals and then the bottom row termi-
nals as shown. With the ground speed control lever
in neutral (switch depressed) both rows should have
continuity.
4. Move the ground speed control lever out of neutral
(switch not depressed).
5. Touch one probe to each of the top row terminals and
then the bottom row terminals as shown in Figure 33.
With the ground speed control lever in forward
(switch not depressed) both rows should have no
continuity.
