Any of the following fail to light: head-light, high beam indicator light, taillight, licence plate light, storage box light, aux-iliary lights or meter light.
Н Measure the voltage (DC 12 V) of yellow 1 or green 3 at the headlight coupler (wire harness side) and yellow at the meter assembly coupler (wire harness side).
Н Is the voltage within specification?
YES
NO
This circuit is OK.
The wiring circuit from
the main switch to the
headlight coupler or
meter assembly cou-
pler is faulty and must
be repaired.
