PT/T Switches
1. Operate each PT/T switch in the UP and DOWN direction and
verify audible "clicking" is heard at UP solenoid switch (1) and
DOWN solenoid switch (2). If all PT/T switches function properly,
proceed with Solenoid Switches. Test suspect PT/T switches as
follows:
• Disconnect UP solenoid lead (3) and DOWN solenoid lead (4) at
the bullet connectors closest to the solenoids.
• Place UP solenoid lead (3) in contact with solenoid terminal (5)
and verify the solenoid "clicks." Place DOWN solenoid lead (4) in
contact with solenoid terminal (6) and verify the solenoid
"clicks." If the solenoids now "click," the PT/T switch or wiring
may be defective, proceed with step 2.
2. Disconnect the suspect PT/T switch leads at the bullet connectors
closest to the PT/T switch and test as follows using ohmmeter:
• Verifycontinuity between the PT/T switch RED lead and PT/T
switch SKY BLUE or BLUE lead when switch is in the UP
position.
• Verify continuity between PT/T switch RED lead and PT/T switch
PINK lead when switch is in the DOWN position.
If test results vary, replace the PT/T switch.
Solenoid Switches
1. Disconnect UP solenoid lead (3) and DOWN solenoid lead (4) at
the bullet connectors closest to the solenoids.
2. Disconnect the RED leads from solenoid terminals (5) and (6).
3. Disconnect the PT/T motor leads from the solenoid terminals.
4. Proceed as follows:
Models 40 and 50 and new style PT/T:

• Connect ohmmeter across UP solenoid terminals (7) and (8) and
verify continuity is present when solenoid is OFF. Then place UP
solenoid lead (3) in contact with the RED lead that was
disconnected from terminal (5) and verify no continuity when
solenoid is ON.
• Connect ohmmeter across UP solenoid terminals (7) and (5) and
verify no continuity when solenoid is OFF. Then place UP
solenoid lead (3) in contact with the RED lead that was
disconnected from terminal (5) and verify continuity is present
when solenoid is ON.
