Actuator
CONTROL CABLE FREEPLAYCable Freeplay Check:
1. Check that cable freeplay is less than 0.39 in (10 mm).
2. If necessary, adjust freeplay.
RESISTANCE TEST
Resistance Check:
1. Check resistance between terminals 1 and 2. It should be approximately 30 ohms.
2. Check resistance between terminals 1 and 3. It should be approximately 68 ohms.
3. If not as specified, replace actuator.
OPERATION TEST
Actuator Operation Check:
1. Connect battery positive to terminals 2 and 3. Connect negative to terminal 1.
2. Slowly apply vacuum from 0 - 11.81 inHg (0 - 300 mmHg) and check that control cable can be pulled smoothly.
3. With vacuum stabilized, check that cable does not return.
4. Disconnect terminal 2 or 3. Check that control cable returns to original position and vacuum returns to zero.
5. If operation is not as specified, replace actuator.
