Test # 9 - Checking the Solenoid
TEST # 9CHECK THE SOLENOID
^ You will need an ANALOG ohmmeter and a 12 volt source for this test.
^ Connect the Black lead of your ohmmeter to the RED wire on the solenoid.
^ Connect the RED lead of your ohmmeter to the BLACK wire on the solenoid. If you have a one-wire solenoid then connect the RED lead of your ohmmeter to the solenoid body.
^ With the ohmmeter set at ohms times one (Rx1), the reading should be no less then 20 ohms, but not infinite.
^ Connect the RED lead of your ohmmeter to the RED wire on the solenoid and the Black lead to the Black wire or body (You're just switching your connections).
^ The ohmmeter should read less than the reading in the first test.
^ Connect the solenoid to a 12 volt source. BE SURE TO OBSERVE PROPER POLARITY, if using a car battery.
^ With lung pressure (or very low pressure) try to blow through the solenoid. It should be sealed.
^ Disconnect the 12 volt source and you should now be able to blow through the solenoid.
