Replace or fix the wiring.

YES

go to 11

- Connect the stepper connector.

Repeat the continuity check with the tool pins.

14-24 = ~ 51

Ω

6-21 = ~ 51

Ω

YES

go to 16

go to 15

Check wiring and connectors more carefully.

- Connect the controller connector.

Set the switch to "ON" with switch to "RUN" and
side stand raised. Repeat the "ON" "OFF" "ON"
switching.

Check the presence of voltage pulses on the
stepper command lines.

Setup for direct voltage measurements.

14-24 = V (pulses for a few seconds)

6-21 = V (pulses for a few seconds)

NOTE:

pulses are used to change the stepper

position.

After reaching the optimum position, the power
supply voltage becomes null.

YES

go to 17

go to 18

- The stepper circuit is efficient.

Check the controller connection connector. Replace the controller if needed.
