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
solenoid, 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
terminal 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 battery. (See motor test procedure, Page 17).
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 sole-
noid 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.
