TEST PROCEDURE FOR SOLENOIDS
Steps to follow when testing current flow through DC solenoids.
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 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 the 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.
8. To test the upper contacts use the same
hook-
up except use the top terminals.(See figure 2).
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
terminals are
connected.
Take care not to bring hot wires into contact with
ground in order to prevent electrical arcing.
