C. Turn the caster fork by hand until it is square with the machine (straight).
Using a multimeter (DC voltage setting), 2.0 – 3.0 VDC should be present
at both sensor connector pins 3 and 6.
D. Turn the rear caster fork by hand fully to the left (counterclockwise).
Using a multimeter (DC voltage setting), 3.7 – 3.9 VDC should be present
at sensor connector pin 3 and 1.1 – 1.3 VDC should be present at sensor
connector pin 6.
E. Turn the rear caster fork by hand fully to the right (clockwise). Using
a multimeter (DC voltage setting), 1.1 – 1.3 VDC should be present at
sensor connector pin 3 and 3.7 – 3.9 VDC should be present at sensor
connector pin 6.
7. Replace the steering position sensor if necessary. The sensor and the
magnetic bolt are matched by the manufacturer and must be replaced as a
set.
8. Align the rear caster fork and adjust the sensor air gap; refer to
