Vacuum Pump/Gauge, 0 - 30 in.Hg

1. Disconnect the actuator cable from the actuator rod and disconnect the 4P connector (A).
2. Connect battery power to the No.4 terminal and ground the No.1, No.2 and No.3 terminals.
3. Connect a vacuum pump to the vacuum hose, then apply vacuum to the actuator.
4. The actuator rod (A) should pull in completely. If the rod pulls in only part-way or not at all, check for a leaking vacuum line or defective
solenoid.
5. With voltage and vacuum still applied, try to pull the actuator rod out by hand. You should not be able to pull it out. If you can, it is defective.
6. Disconnect ground from the No.3 terminal. The actuator rod should return. If it does not return, but the vent hose and filter are not plugged, the
solenoid valve assembly is defective.
7. Repeat steps 2 through 5, and disconnect ground from the No.1 terminal. The actuator rod should return. If it does not return, but the vent hose and
filter are not plugged, the solenoid valve assembly is defective.
