2. Speed sensor
S Connect the pocket tester (DC 20 V) to the
speed sensor coupler (wire harness side)
as shown.
Replace the speed
sensor.

S Turn the main switch to “ON”.
S Elevate the rear wheel and slowly rotate it.
S Measure the voltage (DC 5 V) of blue and
white/yellow. With each full rotation of the
rear wheel, the voltage reading should cycle
from 0.6 V to 4.8 V to 0.6 V to 4.8 V.
S Does the voltage reading cycle correctly?
3. Voltage
S Connect the pocket tester (DC 20 V) to the
meter assembly coupler (wire harness
side) as shown.
Replace the meter
assembly.

Positive tester probe ! yellow/blue
Negative tester probe ! black/white

S Turn the main switch to “ON”.
S Elevate the rear wheel and slowly rotate it.
S Measure the voltage (DC 5 V) of yellow/blue
on the meter assembly coupler (wire har-
ness side).
S Is the voltage within specification?
