Brake Light Switch (Hydraulic); Parking Brake Switch - Polaris RANGER EV 2015 Service Manual

BRAKE LIGHT SWITCH (HYDRAULIC)

VOLTAGE LEVEL: 14.0 VDC
LOCATION: On master cylinder under the hood.
SYSTEM WIRING DIAGRAM REFERENCE: N/A
OVERVIEW: The hydraulic brake light switch contacts
close when brake pedal is applied, connecting the OR
wire to ground.
Brake Light Switch Test
NOTE
Air in the hydraulic brake system could affect switch
operation. Be sure system is purged of all air and
functioning properly before testing the switch.
1. Disconnect wires from hydraulic brake switch.
2. Connect an ohmmeter across switch contacts.
Reading should be infinite (OL).
3. Apply foot brake. The switch contacts should have
good continuity (less than .5 Ohms).
4. Bleed hydraulic brake system if switch is replaced
(see Chapter 7).
Brake Light Switch Power Supply Test
5. Turn key switch ON. Be sure cargo box wire harness
is connected. Disconnect wires from hydraulic brake
switch.

6. Connect an DC voltmeter to the OR (+) and BN (-)
wires. 12-14 volts should be present.

PARKING BRAKE SWITCH

VOLTAGE LEVEL: 14.0 VDC
LOCATION: On park brake lever mechanism under the
dash.
SYSTEM WIRING DIAGRAM
Parking Brake System Wiring Diagram, page 8.30.
OVERVIEW: The switch is OPEN when park brake lever
is not applied. When parking brake is applied, switch
contacts close, connecting the OR/RD wire to ground,
illuminating the park brake lamp. The ground is also
sensed by the Vehicle Control Interface Module (VCIM)
(to prevent differential solenoid operation) and by the
Controller to regulate drive motor output.
NOTE
If the parking brake is applied, the controller will not
send power to the drive motor, preventing drive-away
with the parking brake applied.
Parking Brake Switch Test
1. Release the parking brake lever (completely
forward). Disconnect wire harness from parking
brake switch.
2. Connect an Ohmmeter to the switch terminals.
Reading should be infinite (OL).
