NOTE: The following wire color code and func-

tion description will assist in using the Main Har-
ness and Hood Harness wiring diagrams in this
section. Note that some colors are numbered.
When a numbered color appears on either of the
wiring diagrams, refer to this color code descrip-
tion page, and it will provide you with additional
information.

 Color

 FUNCTION — DESCRIPTION

Brown

Electrical Common; Chassis Ground

The brown wire is connected to the chassis

at the engine stator plate and also through

the voltage regulator chassis bolt (prior to

1989, the taillight harness also had a chas-

sis connection). The headlight bracket is

grounded on some models to reduce the

bracket RFI emissions. All brown wires are

common ground.

Yellow

AC Power; 13 Volts AC (Alternating 

Current)

The yellow wire is connected to the engine

stator plate lighting coil and the voltage reg-

ulator. The voltage produced by the lighting

coil is very engine RPM dependent. The

voltage regulator is necessary to maintain

13.5 VAC on the yellow wire whenever the

engine exceeds about 3000 RPM. All yel-

low wires are 13 VAC. The signal on the

yellow wire is AC. Not only is the voltage

level of this signal RPM dependent, but the

signal frequency (cycles per second) is

RPM dependent as well. The electric

tachometer uses this changing frequency

phenomenon to indicate the engine RPM.

An electric tachometer will operate properly

when connected to any yellow (13 VAC)

and brown (common ground) wire pair.

White

Headlight Low Beam

The white wire connects the dimmer switch

to the headlight bulb. The low beam fila-

ment will illuminate when the dimmer switch

connects the white wire to 13 VAC power.

Blue

Headlight High Beam 

and Indicator Light

The blue wire connects the dimmer switch

to the headlight bulb. The high beam will

illuminate when the dimmer switch con-

nects the blue wire to 13 VAC power. Some

models use a tachometer with a high beam

indicator light. The high beam indicator light

will also illuminate when the dimmer switch

connects the blue wire to 13 VAC power.

COLOR

FUNCTION — DESCRIPTION

Violet 

Ignition System “Shut-Off”

The violet wire connects the ignition system

CDI module to the throttle control switches.

Ignition spark is interrupted when any of the

switches close, connecting the violet wire to

a common ground.

Red/White 

#1

High Temperature Warning Light

Some models use a speedometer with a

high temperature warning light. The red/

white #1 wire connects the high tempera-

ture sensor to the temperature warning

light. The “temp” light will illuminate when

the sensor connects the red/white #1 wire

to common ground.

Red/White 

#2

Solenoid Coil Power

The red/white #2 wire connects the ignition

switch (12 volt DC) power to the solenoid.

The solenoid will activate when the ignition

switch connects the red/white #2 wire to the

+ 12 VDC battery power.

Red #1

Brakelight

The red #1 wire connects the brake control

assembly switch to the brakelight filament.

The brakelight will illuminate when the

brake switch connects the red #1 wire to 13

VAC power.

Red #2

Electric Start Battery Power; 
12 Volts DC (Direct Current)

The red #2 wire connects the battery posi-

tive post (+12 VDC) to the ignition switch

through the fuse holder. All electric start red

#2 wires are +12 VDC. If the fuse “blows,”

all red #2 wires are disconnected from the

battery and battery charging (via the charg-

ing diode) discontinues until the fuse is

replaced.

Red #3

Low Oil Warning Light

The red #3 wire connects the low oil sensor

to the “oil” warning light. The “oil” light will

illuminate when the sensor connects the

red #3 wire to 13 VAC power.

Gray

Electric Fuel Level Gauge

Some models are equipped with an electric

fuel level gauge. The gray wire connects

the in-tank resistive sensor to the gauge.

As the fuel level rises, the sensor resis-

tance decreases, and the gauge needle

rises; conversely, as the fuel level goes

down, the sensor resistance increases, and

the gauge needle drops.

Orange

Reverse Alarm

Some models are equipped with a reverse

gear and reverse alarm. The orange wire

connects the reverse switch to the reverse

alarm. The reverse alarm will “beep” when

the switch connects the orange wire to 13

VAC power.
