Electrical System

The electrical connections should be checked periodi-
cally for proper function.
TESTING ELECTRICAL
COMPONENTS
All electrical tests should be made using the CATT II or a
suitable multimeter. The CATT II can return data for cer-
tain components which are identified at the beginning of
their respective sub-section. If any other type of meter is
used, readings may vary due to internal circuitry. When
troubleshooting a specific component, always verify first
that the fuse(s) are good, that the LED(s) are good, that
the connections are clean and tight, that the battery is
fully charged, and that all appropriate switches are acti-
vated.

NOTE: For absolute accuracy, all tests should be
made at room temperature of 68° F.

NOTE: Certain components and sensors can be
checked by using the EFI diagnostic system (see EFI
Diagnostic System in this section for more informa-
tion).

Battery

Component data can be retrieved using the CATT II. Uti-
lize the Sensor Data screen.

NOTE: Preliminary checks may be performed on
this component using the diagnostic mode on the
LCD gauge (see EFI Diagnostic System in this sec-
tion)
The battery is located under the seat.
After being in service, batteries require regular cleaning
and recharging in order to deliver peak performance and
maximum service life. The following procedures are rec-
ommended for cleaning and maintaining sealed batteries.
Always read and follow instructions provided with bat-
tery chargers and battery products.

NOTE: Refer to all warnings and cautions provided
with the battery or battery maintainer/charger.
Loss of battery charge may be caused by ambient tem-
perature, ignition OFF current draw, corroded terminals,
self discharge, frequent start/stops, and short engine run
times. Frequent winch usage, snowplowing, extended
low RPM operation, short trips, and high amperage
accessory usage are also reasons for battery discharge.

Charging/Maintenance Charging
! WARNING
Any time service is performed on a battery, the following
must be observed: keep sparks, open flame, cigarettes,
or any other flame away. Always wear safety glasses.
Protect skin and clothing when handling a battery. When
servicing battery in enclosed space, keep the area well-
ventilated. Make sure battery venting is not obstructed.

NOTE: When charging a battery in the vehicle, be
sure the ignition switch is in the OFF position.
1. Clean the battery terminals with a solution of baking
soda and water.

NOTE: The sealing strip should NOT be removed
and NO fluid should be added.
2. Be sure the charger and battery are in a well-venti-
lated area. Be sure the charger is unplugged from the
110-volt electrical outlet.
3. Connect the red terminal lead from the charger to the
positive terminal of the battery; then connect the
black terminal lead of the charger to the negative ter-
minal of the battery.
4. Plug the battery charger into a 110-volt electrical
outlet.
5. Trickle charge the battery at 3 amps for 5-10 hours.
If the battery becomes hot to the touch, stop
charging. Resume after it has cooled.
6. Once the battery has reached full charge, unplug the
charger from the 110-volt electrical outlet.

NOTE: If, after charging, the battery does not per-
form to operator expectations, bring the battery to an
authorized Toro ROV dealer for further troubleshoot-
ing.
Accessory Receptacle/
Connector

NOTE: This test procedure is for either the recepta-
cles or the connectors.
VOLTAGE
1. Turn the ignition switch to the ON position; then set
the meter selector to the DC Voltage position.
2. Connect the red tester lead to the red/white wire or
the positive connector; then connect the black tester
lead to ground.
3. The meter must show battery voltage.

NOTE: If the meter shows no battery voltage, trou-
bleshoot the battery, fuse, receptacle, connector, or
the main wiring harness.
