FLOW SENSOR HARNESS RESISTANCE

Isolate Mains Power to appliance as per TOPs P4

Set Multimeter to Resistance

Disconnect connector X2 from the PCB

Measure the resistance across pin 3 (gold wire) on the 24 way connector (X2) on the PCB to a suitable earth point.

Resistances vary with temperature and should conform approximately to the table below:

Note: Clicking on the resistance table will switch between table and graph view.
