Spark Ignition in Gas Cookers?

Interesting

But i doubt it would be dangerous at the kind of current levels your talking about. Electric fences run at 1000s of volts and arnt lethal its just they dont carry much current.

Incidentally you can get a little shock of those piezo ignition things in lighters. If you take the mechanism out there are contacts at each end and if you squeeze it between thuimb and forefinger you get a shock .

I recieved my second mains shock 2 days ago, first was from a flymo cable (mum had half cut through it and i picked it up) and the second was fixing my bros light while the power was still on. I really should be more careful . Just goes to show that mains electrisity isn't as dangerous as you think

Going back to the subject of 'Spark Ignition in Gas Cookers'....

I have a 'spark ignition' which is not igniting.. It always used to work fine but then stopped.. I have tried new batteries but no joy.. When the button is pressed I can hear a 'whine' but no spark.. If I hold a screwdriver across the gap on one of the hobs, and move it about it about a bit, and then press the 'ignitor' button, I can get it to spark on the others.

Also, if I open up the battery compartment (1 x AA 1.5v battery) and connect 2 x 1.5v batteries, and press the ignitor switch, sparks are created very quickly(!) - approx. 5 every second, instead of about once a second!

Any thoughts?? Has something broken?

Please post your thoughts.. cos it's only a matter of time till I blow myself up with a box of matches!

I would guess that your piezo is fading, (if that's possible). I'm no expert here, but if it was me I'd either try and google a new ignition unit for your cooker. Or go and by a cheap battery holder from Maplins wire it in and run it on 2xAA if you say that works.

Or do the igniters (the sparky bits on on the hob itself) just need de-gooing?

If its pizeo ignotion, theres no battery needed

DONT over-volt the ignition electronics. Its really not a good idea. Whats probably happening is the high voltage side is MUCH higher (double) than the components are rated for, and they are shorting out, causing it to be quicker.

There is a battery needed.. In the instructions, it says use an EveryReady R6S - is this a 'high power' 1.5v battery?

Does it sound as thought it is just the battery causing it not to work?

I wish I understood these things

If theres a battery,then theres no need for any pizeos atall. With a battery it would just use a transformer and an ossicillating circuit, to get high voltage.

Try replacing the battery and if it doesnt work properly then, theres not much you can do.
