CONDITION
Regulator: Critical
Voltage Too High
32523
15
P160D
This Trouble Code Sets if the Regulator
has detected Excessive Voltage in the
Critical Circuit. Can be caused by
damaged wiring, faulty headlight, Fuel
Pump or Regulator connections.

This Trouble Code Sets if the Regulator
has detected Low Voltage in the Chassis
Circuit. Can be caused by damaged wiring
or faulty grip heaters.
Regulator: Chassis
Short Circuit
32523
22
P160F
This Trouble Code Sets if the Regulator
has detected Excessive Current Draw in
the Chassis Circuit. Can be caused by
damaged wiring or faulty grip heaters.
Regulator: Chassis
Voltage Too High
32523
31
P1610
This Trouble Code Sets if the Regulator
has detected Excessive Voltage in the
Chassis Circuit. Can be caused by
damaged wiring, Regulator connections or
Regulator.
Regulator: Stator
Output Low

36
P1510
This Trouble Code Sets if the Regulator
has detected a Low Voltage condition in
the Stator. Can be caused by a Short to
ground in the Stator or damaged Stator
wiring.
Regulator: Stator
Open Circuit
32531
37
P1511
