THROTTLE CONTROL SWITCH WILL NOT OPERATE (SEE).

NOTE

Vehicle MASTER disconnect switch must be ON and ignition switch set to ON.

Failure to do so will cause erroneous results.

Refer to wiring diagram (page 3-258) for all wiring repair steps.

Step 1.

Check for +24 VDC between wire 70T (1) and ground at tool switch (2).

If +24 VDC is not present, repair wiring 70T between tool

switch and connector X.

+24 VDC is present, go to step 2.

Step 2. With tool switch (2) pulled on, check for +24 VDC between wire 71V (3)

and ground at tool switch.

If +24 VDC is not present, replace tool switch (page 4-162).

If +24 VDC is present, go to step 3.
