LIGHTING SYSTEM

 

 

Above circuit diagram shows only lighting circuit in wiring diagram.

 

B. Lighting Tests and Checks

The battery provides power for operation of the headlight, taillight, and meter lights. If none of the above operates, always check battery voltage before proceeding further. Low battery voltage indicates either a faulty battery, low battery water, or a defective charging system. See "CHARGING SYSTEM" for checks of battery and charging system. Also check fuse condition. Replace any "open" fuses. There are individual fuses for various circuits (see complete Circuit Diagram).

NOTE:

Check the headlight bulb first before performing the following check.

1. Headlight check

NOTE:

When the main switch is turned to "ON", the headlight and meter lights come on automatically and the lights stay on until the ignition switch is turned to "OFF" even if the engine stalls.

HEADLIGHT DOES NOT COME ON WHEN ENGINE IS RUNNING

Check the headlight butb.

----------->
Faulty

Replace the bulb.

▼
Bulb OK

▼

Check the continuity of dimmer switch 1L/B-Y, L/B-G wires).

 ----------->
Open

Replace the switch.

▼

OK

▼

Check the continuity of starter switch (R/Y- L/B wire).

 ----------->
Open

Replace the switch

▼

OK

▼
Check the headlight fuse ----------->
Open		 Replace the fuse.

▼

OK

▼
Check the continuity of main switch (R-Br wire). ----------->
Open		 Replace the switch.

▼

OK

▼
Check the main fuse. ----------->
Open		 Replace the fuse.

▼

OK

▼
Check battery voltage ----------->
Low		 Charge or replace

▼

OK

▼
Faulty grounding or faulty connection of headlight switch

 

HIGH BEAM AND/OR LOW BEAM DO NOT LIGHT

Check for battery voltage at dimmer switch terminal

----------->
No voltage

Dimmer switch defective

▼

Voltage OK

▼

Check for battery voltage at headlight high beam or low beam terminal

----------->
No voltage

Open or poor connection between headlight and dimmer switch terminal

▼

Voltage OK

▼

Poor ground or poor connection of headlight wiring

2. Taillight does not work:

a. Check bulb

b. Check for 12V on blue wire.

c. Check for ground on black wire to tail/brake light and/or license light assembly.
