BBQ Igniter Help!!

Hi
I have a BBQ igniter circuit from my grandpas BBQ, it dose not work any more, it has 2 transistors, a large coil inside some plastic, and a large blue square capacitor, i dont know much about these circuits and was wondering if anyone could help me,

Thanks Chris

 

What brand and model of BBQ is it.

 

it is captain cook i am in australia if that helps, and if you know a sort of circuit that will make the same spark that will also work

 

I am not familair with Captain Cook BBQ Grills. Weber BBQ grills use Piezo Igniters (Cheap, no batteries, reliable - mine is 12 years old and still works).

Sometimes fixing an old ciruit is more of a hobby to learn something, but just buying a replacement part is cheaper.

Sounds like a capacitor discharge ignition. Does it have a low voltage battery? Transistors might be part of oscillator to charge cap. Might be a close cousin to the Electric Match.

 

ok bernard does that provide a constanrt spark? Could you post a better picture sorry thanks, chris

 

Drawing is from memory, and that's not getting better. Each push of the switch prodeces a spark. The cap. probably around 200μF or bigger, spark coil like used in model airplane engines of the 1940's. I may still have it somewhere. Every thing in use now is piezeo.
