• Move a screwdriver back and forth across the pick-up surface
of the speed sensor. The voltage readings should cycle as fol-
lows (0 V
→
12 V or 12 V

change, replace the speed sensor with a new one.
NOTE:
While testing, the highest voltage reading should be the same as
the battery voltage (12 V).
