Testing Voltages to Check Electronics
1. WHITE
2. PURPLE
3. BLUE
9. BLACK
4. GREEN
5. YELLOW
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
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.
