Test Procedure 20 - Accelerator Limit Switch Wire Continuity (Green/White and Blue
Wires)
1. Turn the key switch to OFF and place the forward and reverse switch in NEUTRAL. Disconnect the bat-
teries and disconnect the Z plug from the controller.
2. Remove the two hex head screws (20) attaching the potentiometer cover and remove the cover (Figure
21-51).
3. Disconnect the green/white wire and the blue wire from the accelerator limit switch (Figure 21-52).
4. Place the black (-) probe of a multimeter, set to ohms (
Ω
), on the green/white wire terminal end (that
was removed from the limit switch) and place the red (+) probe in the Z8 (green/white wire) connector
position on the Z plug (Figure 21-53). The reading should be continuity. If the reading is incorrect,
repair or replace the green/white wire. Make sure that the green/white wire is in the Z8 position on the
Z plug, and that the wire terminal pin is secure in the Z plug.
5. Remove the center dash. See Page 20-26.
6. Place the black (-) probe of a multimeter, set to ohms (
Ω
), on the blue wire terminal end (that was
removed from the limit switch) and place the red (+) probe on the key switch terminal with the blue wire
attached. The reading should be continuity. If the reading is incorrect, repair or replace the blue wire
(Figure 21-54).
Test Procedure 21 - Accelerator Limit Switch Continuity
1. Turn the key switch to OFF and place the forward and reverse switch in NEUTRAL. Disconnect the bat-
teries and leave the Z plug connected to the controller.
2. Remove the two potentiometer cover mounting screws (20) and remove the potentiometer cover (Fig-
ure 21-51).
3. Disconnect the blue wire and the green/white wire from the potentiometer limit switch (Figure 21-52).
4. Place the black (-) probe of a multimeter, set to ohms (
Ω
), on one terminal of the limit switch and place
the red (+) probe on the other terminal of the limit switch (Figure 21-55, Page 21-40). The reading
should be no continuity. If the reading is incorrect, replace the limit switch.
5. With the key switch OFF, and the forward and reverse switch in NEUTRAL, slowly depress the acceler-
ator pedal to the floor. The limit switch should click and the reading should be continuity. The limit switch
should be replaced if either of these conditions exists:
- The limit switch clicks and there is no continuity.
- The limit switch does not click.
