TEST PROCEDURE FOR SOLENOIDS

Steps to follow when testing current fl ow through DC solenoids. It should be noted that when test-
ing a 12 volt or 24 volt solenoid, the DC motor and battery must of the same voltage.

To test the solenoids: (See Figure 1).

1. Securely clamp a motor to a bench or work surface.

2. Attach a #6 gauge jumper wire from “A” terminal on the motor to one of the fi eld terminals on

the motor, (F-2).

3. Attach the other motor fi eld terminal (F-1)to one of the side terminals of the solenoid.
4. Ground the solenoid to the motor with a wire as shown.
5. Attach positive (+) battery wire to the opposite side terminal of solenoid.

Ground the negative (-) battery wire to the motor

isolated ground terminal

6. Touch “hotwire”, from the positive battery terminal, to small terminal of the solenoid.
7. The motor should now be running if the solenoid is good. If not, make sure the motor will

run directly from the battery. (See motor test procedure page 23).

8. To test the upper contacts use the same hookup except use the top terminals. (See

Figure 2). When hooked up as shown in Figure 2, motor should start running. When the

“hotwire” is touched to the small terminal the motor will stop operating.

The top terminals are normally closed; ie: connected, and the side terminals open, or not
connected. When the solenoid operates, the top terminals are disconnected and the side
terminals are connected.

Take care not to bring hot wires into contact with ground in order to prevent electrical arcing.
