Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Remove connector 35 from the PCB
Measurement:
Test 1.
Measure for resistance across the blue and brown wires of connector 35.
Expected resistance approximately 4.2 KOhms.
Test 2:
Measure the resistance between the blue and earth wires of connector 35.
Expected resistance greater than 1 MOhm.
Note.
A reading of O.L is acceptable as this is greater than 1MOhm.
