LIGHTING SYSTEM
CHECKING THE TAILLIGHT
(LEDs)
1. Disconnect the taillight coupler.
2. Connect two jumper leads "1"
from the battery terminals to the
respective coupler terminal as
shown.
3. Check:
• LED (for proper operation)
Does not light→Replace the tail-
light assembly.
• A wire that is used as a jumper
lead must have at least the same
capacity of the battery lead, oth-
erwise the jumper lead may burn.
• This check is likely to produce
sparks, therefore, make sure no
flammable gas or fluid is in the
vicinity.
CHECKING THE AC MAGNETO
1. Inspect:
• Lighting coil resistance
Out of specification→Replace.CHECKING THE RECTIFIER/
REGULATOR
1. Connect the battery leads.
2. Start the engine.
3. Turn on the headlight and taillight
by turning on the light switch.
4. Inspect:
• Out-put voltage
Out of specification→Replace
rectifier/regulator. Battery (+) terminal→Blue lead
"2"
Battery (-) terminal→Black lead
"3"
Tester (+) lead→Yellow lead "1"
Tester (-) lead→Ground "2"
