2. Connect the red MaxiClip and meter lead to the

black/white servo terminal; then connect the black

MaxiClip and meter lead to the yellow servo termi-

nal.

3. Rotate the servo clutch counterclockwise. The ohms

should increase as the clutch is rotated until it

reaches 4700-5000 ohms.

4. Continue the clutch rotation, and there will be a

small area in the rotation where the ohm reading will

disappear; then it will return again.

5. Continue the clutch rotation, and the ohms should

appear at a very low value but will again increase to

4700-5000 ohms. This is normal operation.

FZ088A

6. Install the servomotor.



NOTE: If the servo operates correctly and the

potentiometer test is correct but fails to operate when

connected to the ECM/regulator/rectifier at the desig-

nated RPM, see Troubleshooting Servomotor chart in

this section.
