Testing Voltages to Check Electronics
1. WHITE
2. PURPLE
3. BLUE
4. GREEN
5. YELLOW
9. BLACK
8. BROWN
6. ORANGE
7. RED
CAUTION! Improper alignment of connector plug can cause system failure. USE
EXTREME CARE when making connection. Unit MUST BE DISCONNECTED
FROM POWER SOURCE before connecting.
Measuring voltages present at wall plate control will aid in determining damaged circuitry in
electronics housing.
Set voltage meter to DC and touch black meter lead (-) on meter to #9 screw terminal on wall plate
connector. (Black wire - ground)
Touch red meter lead (+) to each of the colored wires listed below.
1. White wire voltage range 4.8 VDC - 5 VDC.
(4.7 would indicate damaged circuitry in the electronics housing — replacement of electronics
housing needed.)
Symptom: Unit may not park.
2. Purple wire voltage range 4.8 VDC - 5 VDC.
(4.7 would indicate damaged circuitry in the electronics housing — replacement of electronics
housing needed.)
Symptom: Unit may fail to rotate or elevate.
3 - 6. Blue, green, yellow, orange. These wires should measure .5 VDC or 1.8 VDC, depending on
switch states.
7. Red wire will read supply voltage to the unit when wall plate is switched on.
8. Brown wire will read primary voltage supplied to unit (11 to 13.8 VDC)
9. Black wire is ground.
