6 PROBLEM SOLVING
6.3 ELECTRICAL CIRCUITS ____________________________________________________
When troubleshooting the mower using the controller
always check that Program Select (2) lamp is on. This
indicates that the controller has power and the program is
active.
NOTICE
The controller requires a minimum of six volts to
operate.

Individual circuits can be tested by operating an input
switch, checking for the required input signal and looking
for a corresponding output. Keep in mind that not all
switches are located on the instrument panel. The
traction pedal and reel lift limit are controlled by small
proximity switches mounted on the frame of the mower.
If an input lamp does not light, an inactive condition is
indicated. This could be caused by a fuse, faulty switch
or poor connection.
