• Set the main switch to “ON”.
• Elevate the front wheel and slowly rotate
it.
• Measure the voltage (DC 5 V) of gray and
gray/black. With each full rotation of the
front wheel, the voltage reading should
cycle from 0.6 V to 4.8 V to 0.6 V to 4.8 V.
• Does the voltage reading cycle correctly?
Replace the speed
sensor.
