Checking the speed sensor

1. Check:

Speed sensor output voltage Out of specification → Replace.

a. Connect the pocket tester (DC 20 V) to the speed sensor coupler (wire harness end) as shown.

• Positive tester probe gray "1"
• Negative tester probe gray/black "2"

b. Set the main switch to "ON".

c. Elevate the front wheel and slowly rotate it.

d. Measure the voltage of gray and gray/black.

With each full rotation of the front wheel, the voltage reading should cycle from 0 V to 5.0 V to 0 V to 5.0 V.
