Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Hinge down the PCB housing
Disconnect the rectification lead from the condensate trap
Disconnect the 6 way connector from the PCB
Disconnect the rectification lead from the condensate trap
Disconnect the 6 way connector from the PCB
Measurement:
Measure the resistance between the spade connector disconnected from the condensate trap and connection 1 (white wire) on the Molex connector.
Expect continuity / zero resistance.
Also visually inspect the rectification harness throughout its entire length (including the sections to the condensate trap, rectification electrode and the section to the APS (if fitted) checking there is no damaged insulation and that the connectors are a tight fit.
Are the harness checks satisfactory?
