Fan Motor; Power Distribution Module (Pdm) - Tracker Off-Road 500S Service Manual

4. Depress the reverse override switch. The meter must
show near zero volts.
5. Select "LOCK" on the drive select switch. The meter
must show battery voltage.
6. Depress the reverse override switch. The meter must
show near zero volts.
 NOTE: If the voltage readings are correct and a
momentary "whirring" sound is not heard from the
front drive actuator, check voltage at the actuator
connector. If voltage readings are correct and the
actuator doesn't operate, the actuator must be
replaced.

Fan Motor

This component can be tested using the Dealer Diag-
nostic Service. Utilize the Test screen.
NOTE: Preliminary checks may be performed on

this component using the diagnostic mode on the LCD
gauge (see EFI Diagnostic System in this section).
NOTE: To determine if the fan motor is good, dis-

connect the fan connector; then connect the blue wire
from the fan connector to the positive side of a 12-volt
battery of similar output as the vehicle. Connect the
black wire from the fan connector to the negative side.
The fan should operate.
PK296
! WARNING
Care should be taken to keep clear of the fan blades.
NOTE: Fan motor resistance checks are not recom-

mended. Resistance values change with the motor
commutator position.
Power Distribution Module
(PDM)
NOTE: The module and wiring harness are only

serviceable as assemblies.
If there is any type of electrical system failure, always
check the fuses first.
104
NOTE: The fuses are located in a power distribu-

tion module under the hood.
NOTE: Make sure the fuses are returned to their

proper position according to amperage. Refer to the
amperage listed under each fuse on the power distri-
bution module.
1. Remove the cover from the power distribution mod-
ule.
NOTE: To remove a fuse, compress the locking tabs

on either side of the fuse case and lift out.
UTV-253
CAUTION
Always replace a blown fuse with a fuse of the same
type and rating.
2. Set the meter selector to the DC Voltage position.
3. Connect the black tester lead to battery ground.
4. Using the red tester lead, contact the top of each side
of each fuse.
PK293
5. The meter must show battery voltage from both sides
of each fuse.
NOTE: When testing the high beam, the headlight

switch must be in the high-beam position. When test-
ing the low beam, the headlight switch must be in the
low-beam position.
NOTE: If battery voltage is not indicated on both

sides of each fuse, check the fuse, PDM, switches, or
battery, or troubleshoot the wiring harness.
RELAYS
The 4-pin relays are identical plug-in type located on the
power distribution module. Relay function can be
checked by switching relay positions. The 4-pin relays
are interchangeable.
PDM Relay Testing
1. With the ignition switch in the OFF position, remove
the suspected relay from the PDM.
