Panel branch
Alternator branch
Battery branch

Wire Description (wire numbers relate to wires shown in the wire harness diagram)

PANEL BRANCH

Ignition Wire (Brown): Connects to switched voltage source (key switch or oil pressure switch). Must see zero volts when off and minimum of 8.5 VDC to activate.
Lamp/Feature Out Wire (Orange): Remains neutral during normal regulator operation and provides a source of ground to drive warning lamp or alarm if faults are detected. See user Guide for details.
Feature In Wire (White): Can be connected to a voltage source greater than 8.5 VDC to enable a range of selectable optional capabilities as detailed in the User's Guide.

ALTERNATOR BRANCH

Alternator Temperature Sensor: Terminated in two-pin Superseal type connector with green heat shrink. Connects to 45cm (18”) sensor pigtail included with harness. Connect sensor lug to alternator ground post or case bolt.
Alternator Ground (Black): Connects to alternator ground post or to primary ground bus.
Alternator Positive (Red): Connects to primary positive bus, or power post on alternator side of any switches or fusing. See WS500 User's Guide for detailed wiring diagrams. Fuse wire at 15 amps.
Alternator Field (Blue): Connects to alternator external field terminal.
Stator (Yellow): Can be spliced into the alternator's tach output wire or attached to alternator AC/stator tap to enable regulator to determine low alternator RPM.

BATTERY BRANCH

Battery Temperature Cable (Grey two-wire cable. Blue cable heat shrink): Provides a connection point for optional battery temperature sensor. Battery Temperature Sensor sold separately: click on link for 0.3m, 3m or 8m length.

Battery Ground Sense* (Black/Yellow Stripe): Connects to alternator ground post or to primary ground bus.
Battery Positive. Sense* (Red/Yellow Stripe): Connects to primary positive bus, or power post on alternator side of any switches or fusing. See WS500 User's Guide for detailed wiring diagrams. Fuse wire at 3 amps.
Current Sensing** (+) (Purple): Connects to low current machine screw on the side of the current shunt, closest to source of current. See mounting diagram in the WS500 User's Guide. Wire must be fused at 5A if shunt is in the positive cable to batteries.
Current Sensing**(-) (Grey): Connects to low current machine screw on the side of the current shunt, furthest from source of current. See mounting diagram in the WS500 User’s Guide. Wire must be fused at 5A if shunt is in the positive cable to batteries.

* Mounting location of power and voltage sense wires may vary based on individual application. See WS500 User's Guide for wiring diagrams. Note that both power (RED) and voltage sense (RED/YELLOW) must be installed on the alternator side of any switches or fusing in the DC charging circuit.

** Current sensing is calibrated for a 500A/50mv (default) current shunt Installation may depend on whether shunt is installed HIGH or LOW. Refer to User's Guide for recommendations.
