Whats the best way to test the electrode that produces a small amount of current, i did put the m/mtr in amp mode, removed the F2 electrode from the pcb and put the red probe 2 this,
I then placed the com probe on the pcb board and powered the boiler / i got 0 reading on...
Hi i have reset the switch by turning anti clockwise and holding there for 3 secs + when i fitted the replacement board / think this is faulty.....................i have put the old pcb back and the boiler fired up and shut down after 15 secs.
Can someone explain what contacts i need to test...
