CHARGING SYSTEM

CHARGING SYSTEM DIAGRAM

The charging system consists of:.
• Battery
• Stator / Alternator

• Voltage Rectifier / Regulator

VOLTAGE RECTIFIER / REGULATOR
VOLTAGE RECTIFIER / REGULATOR
OVERVIEW
The voltage rectifier / regulator is responsible for
converting AC voltage to DC voltage and controls the DC
output.
NOTE
If the temperature of the regulator / rectifier exceeds
194°F (90°C), the unit will turn itself off to cool down.
The unit will turn on at approximately 167°F (75°C). If
voltage output is equal to or less than static battery
voltage, verify the housing cooling fins are clean, free
from debris and that adequate airflow is present.

NON-HIGH LIFTER MODELS

VOLTAGE REGULATOR REMOVAL
1. Place the vehicle in park.
2. Remove the front rack / storage compartment to allow
access to the battery.
3. Disconnect the battery negative.
4. Disconnect the battery positive.
5. Remove the fasteners retaining the voltage regulator.
6. Remove the center cover under the pod.
7. Remove the seat.
8. Remove the left side panels.
9. Remove the left footwell.
NOTE
This step is only required on 2017 sportsman 850/1000
1-UP machines (excluding High Lifter)
q
10. Locate the stator wires
and disconnect the regulator from the stator.
11. Tape a string or cable to the regulator harness.
NOTE
The rope or cable used should be long enough to allow
the regulator to be fully removed from the front of the
vehicle while leaving some rope or cable exposed at
the footwell. During installation the rope or cable will be
used to properly route the new regulator wiring.
12. Grasp the regulator wiring near the regulator and
slowly remove the wiring harness.
NOTE
Do not apply excessive force while removing the
regulator wiring.
13. Remove the Regulator from the vehicle.
NOTE
Ensure the rope or cable may be grasped and pulled
during assembly as this will be used to install the new
regulator wiring.
VOLTAGE REGULATOR INSTALLATION
(Applies to NON - High Lifter models only)
1. Fasten the rope or cable used during regulator
removal to the NEW regulator wiring harness.
2. Route the regulator harness as it was originally
installed.
NOTE
Do not apply excessive force while installing the
regulator wiring.
