Testing Lighting Voltage at Easy Cube
a. If Hood has an Internal Blower it will need to be
removed to perform this check.
b.
Disconnect two pin Lighting Harness from Easy
Cube connection. (See Figure 4-8).
c.
Measure voltage between pins of connector
inside Easy Cube. Voltage should be 12 VDC.
5. Testing Line Voltage to Transformer and Blower
Motor.
Perform both of these tests with the Blower Motor
and Lights Energized.
a.
Disconnect two pin connector or screws with
two orange wires to Transformer. Measure volt
age between two pins or wires on Power Board
side of connector. Voltage should be 115 VAC.
(See Figure 4-4)
b.
Measure voltage between terminal posts on the
Terminal Block inside Electrical Box. Voltage
should be 115 VAC. (See Figure 4-5)
6. Testing Line Voltage to Transformer on Power
Board.
On Power Board LUX1 is the voltage to
Transformer.
a.
Disconnect LUX1 from Power Board and meas-
ure voltage between the pins on the board.
Voltage should be 115 VAC. (See Figure 4-6)

7. Testing 12 VDC from Transformer Secondary.
Wires in sheath are 12 VDC to LED Assemblies.
The three pin connector is the Lighting Command
Harness. (See Figure 4-7)
a.
Disconnect two pin connector from secondary
side of Transformer. Measure voltage on pins
of Transformer. Voltage should be 12 VDC.
b.
Disconnect three pin connector from secondary
side of Transformer. Measure voltage between
pins that correspond with black and white wire
on the connector. Voltage should be 12 VDC.
c.
Disconnect three pin connector from second-
ary side of Transformer and Power Board.
Check Continuity from each wire in Lighting
Command Harness.
