TEST PROCEDURE FOR SOLENOIDS
Steps to follow when testing current flow through DC sole-
noids.
It should be noted that when testing a 12 volt or 24 volt sole-
noid, the DC motor and battery must be 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 field terminals on the motor, (F-2).
3. Attach the other motor field 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 ter-
minal of solenoid. Ground the negative (-) battery wire to
the motor housing.
6. Touch "hot" wire, 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 bat-
tery. (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 "hot" wire is touched to the small terminal the motor
will stop operating.
The top terminals are normally closed; i.e. connected, and the
side terminals open, or not connected. When the solenoid
operates, the top terminals are disconnected and the side ter-
minals are connected.
Take care not to bring "hot" wires into contact with ground in
order to prevent electrical arcing.
