• Set the main switch to "ON".
• Elevate the rear wheels and slowly rotate
them.
NOTE:
• Rotate the rear wheels by hand.
• The voltage reading should drop to 0 as the
speed sensor magnet approaches the
speed sensor È.
• Measure the voltage (DC 5 V) of blue and
black. With each full rotation of the rear
wheels, the voltage reading should cycle
from 0 V to 4.6 V to 0 V to 4.6 V.

2. Voltage
• Connect the pocket tester (DC 20 V) to the
meter assembly coupler (wire harness
side) as shown.
Positive tester probe → brown/blue 1
Negative tester probe → black 2
• Set the main switch to "ON".
• Measure the voltage (DC 12 V) of brown/
blue 1 on the meter assembly coupler
(wire harness side).
• Is the voltage within specification?
Replace the meter
assembly.
