Electrical Service Notes
Keep the following notes in mind when diagnosing an electrical
problem:
• Refer to wiring diagram for stator and electrical
component resistance specifications.
• When measuring resistance of a component that has a
resistance value under 10 Ohms, remember to subtract
meter lead resistance from the reading. Connect the
leads together and record the resistance. The resistance
of the component is equal to tested value minus the lead
resistance.
• Become familiar with the operation of your meter. Be
sure leads are in the proper jack for the test being
performed (i.e. 10A jack for current readings). Refer to
the Owner’s Manual included with your meter for more
information.
• Voltage, amperage, and resistance values included in
this manual are obtained with a Fluke™ 77 Digital
Multimeter (PV-43568). This meter is used when
diagnosing electrical problems. Readings obtained with
other meters may differ.
• Pay attention to the prefix on the multimeter reading (K,
M, etc.) and the position of the decimal point.
• For resistance readings, isolate the component to be
tested. Disconnect it from the wiring harness or power
supply.
Under-Dash Components
The following switches and components can be accessed
underneath the instrument / dash panel:
• Speedometer
• Digital Wrench Diagnostic Connector
• AWD Switch
• Headlamp Switch
• 12 Vdc Accessory Power Point
• Ignition Switch
• Fuse / Relay Box
SWITCHES / CONTROLS
Brake Light Switch
1. The brake switch can be accessed by removing the driver’s
seat (RZR / RZR S) or the left rear passenger seat (RZR 4).
The switch is located under the outer PVT cover along the
lower frame. The brake pressure switch is installed into the
cross fitting block.
2. Disconnect wire harness from switch and connect an
ohmmeter across switch contacts. The reading should be
infinite (OL).
3. Apply the brake and check for continuity. If there is no
continuity or if resistance is greater than 0.5 ohms, clean the
switch terminals. Re-test and replace switch if necessary.
