Set Multimeter to DC Volts 
Disconnect display harness from the main PCB
| WARNING! - Mains voltage is expected during test follow TOPs P4 live testing procedure |
Measurement:
Measure the dc voltage between the two outer pins on the front of the PCB display connector (jumper side facing out)
Ensure a good contact is made and that the red probe is on the upper pin and the black probe is on the lower pin.
Expect 24.5 vdc or greater.
Notes:
The voltage may fluctuate slightly but should remain above 24.5 vdc.
