Hour Meter
The meter is either located on the control panel or under
the control panel inside the control c onsole.
1. Connect the positive (+) terminal of a 12 VDC source
to the positive terminal of the hour meter.
2. Connect the negative (-) terminal of the voltage
source to the other terminal of the hour meter.
3. The hour meter should move a 1/10 of an hour in six
minutes.
4. Disconnect voltage source from the hour meter.

Electronic Controller(s)
The Toro electronic c ontroller(s) sense the condition of
various switches, such as the seat sensor, c utting unit
down switches, traction neutral switch, etc., and directs
power output to allow certain machine functions, such
as engine run, cutting units engage, etc.
Because of the solid state circuitry built into the control-
ler, there is no method to test it directly. The controller
may be damaged if an attempt is made to test it with an
electrical test device, such as a volt-ohm meter.
IMPORTANT: Before performing welding on the ma-
chine, disconnect both battery cables from the bat-
tery, disconnect both wire harness connectors from
the electronic control unit and disconnect the termi-
nal connector from the alternator to prevent dam-
age to the electrical system.

Parking Brake Switch
The parking brake switch is a proximity switch located
inside the steering tower. When functioning properly,
this feature kills the engine when the forward/reverse
pedal is depressed and the parking brake is On.
The switch is closed to ground (orange/brown wire to
black wire) when the parking brake is Off.
1. With the parking brake engaged, separate the termi-
nal connector and measure resistance between the
switch connector pins. Resistance should read as an
open circuit.
2. Release the parking brake and measure resistance
between the switch connector pins. Resistance should
read as a c losed circuit.
3. Adjust the position of the proximity switch as neces-
sary to obtain the above results.
