Inspect Actuator Vacuum Type

(a) Measure the resistance between terminals as follows. Resistance: 1 - 3 Approx. 68Q 2 - 3 Approx. 30Q

(b) Connect the positive (+) lead from the battery to ter minals 1 and 2, and the negative (-) lead to terminal 3.

(c) Slowly apply vacuum from 0 to 300 mmHg (0 to

11.81 in. Hg, 0 to 40.0 kPa), check that the control cable can be pulled smoothly.

(d) With the vacuum stabilized, check that the control cable does not return. HINT: As you apply and hold the vacuum with the vacuum pump, the drawn-in diaphragm will in some cases return. This does not indicate a malfunction. Actuator leakage is allowable.

(e) Disconnect terminal 1 or 2 and check that the control cable returns to its original position and the vacuum returns to 0 mmHg (0 in.Hg, 0 kPa). If operation is not as specified, replace the actuator.
