How do they work - is there a crystal or a transformer to generate the high voltage? Taking the easy bits of the hob apart - removing the plate with the taps, all I can see is the battery holder, the underside of the switch which is ok, and the 'spark plug' by each of the four burners. I've cleaned them and fitted a new battery, but it still doesn't work. Is there something else, maybe below the burner that I need to loook at?
Thanks

Follow the leads back from the ignitors (spark plugs) thats the generator. Check the input by removing the wires at the gen which come from the switch and battery with a meter if possible, do you have a circuit? if so the generators faulty. If not disconnect the switch and connect these 2 wire together, do you have a circuit now? if so its the switch.
ive found when fixing these things duracell batteries will do the trick where others wont work or quickly fail.
Take care not to get a shock. On mine I have to be careful to ensure the hob top is grounded to the base part - as I found when just lifting the top to take a look.
I cleaned it all, fitted a new battery And replaced switch with one that works. The + from the battery is connected to the switch - checked with meter; no resistance. The other pole of the switch is neither live nor earthed as if it it isn't connected to anything, although the wire runs towards the ignitor. The '-' from the battery connects to earth - all the metalwork of the hop. Nothing is happening at the ignitor.
could it be that all four ignitors are broken?
Thanks

The other side of the switch must go live when the switch is operated - or the switch is faulty. Try bypassing the switch
yes I was a bit vague there...- it does that ok when operated.
