Brake Light Switch; Parking Brake Switch - Polaris Ranger 500 2x4 2007 Service Manual

Differential Solenoid Circuit Operation
Power is present at the AWD / Diff-Lock Switch when the
ignition key is turned "ON".
When the switch is pushed to activate "Turf" mode, power is
sent to the PDM.
The voltage input from the AWD / Diff-Lock Switch signals the
PDM to provide a ground path for the differential solenoid to
activate.

• Check the connector located under the left rear fender.
Look for loose wires or bad connections.
• Check for power from the connector, to ensure the
solenoid has power to be activated.
• Check the operator's switch wires for loose
connections.
• Remove solenoid from carrier and ensure the solenoid
plunger is actuating.

2. Disconnect wire harness from switch.
3. Connect an ohmmeter across switch contacts. Reading
should be infinite (•).
4. Apply foot brake and check for continuity between switch
contacts. If there is no continuity or greater than .5 ohms
resistance when the brake is applied with slight pressure,
first clean the switch contacts and re-test. Replace switch
if necessary.
