Default Condenser or Capacitor

Hi Everyone,
I was wondering where in Australia do we buy replacement Condensers / Capacitors for our magnetos. I notice that on the parent website based in the USA they often mention "NAPA" and quote part numbers like FM200 or FM SXY2433 (the latter has a higher capacity). What do we ask for out here? Condensor or Capacitor? Do we go to places like 'Dick Smiths'?

Hi, I one restored a wico EK - new coils, condensor etc etc. The consensor was a holden car stock item - looks didnt matter as it was all inside and there was plenty of space to fit it.. Mike

Cobbadog:

"Condenser" - "Capacitor". It doesn't matter. They're both the same thing.

Just about any condenser from a "points" type auto ignition system will work fine on a buzz coil or magneto unless it's an oddball design.

In a pinch, you can go to an electronics parts house and get a mylar film 0.22 microfarad 640 volt capacitor and it will work fine.

0.22 microfarad is about in the middle of the capacitance range most ignitions use and, since the spike that comes off of the coil when the points open is several hundred volts, the 640 volt figure gives a little safety margin.

Take care - Elden

Exclamation Re: Condenser or Capacitor

The only real difference you will note using condensers or capaciters, is the transfer of metal from the points. Too much capacity will cause transfer one way, too little, the other, unless you are way off, in which case spark will suffer. A good place to watch metal transfer is on an igniter fired engine. After a great while, metal will transfre from one point to the other. Reversing the polarity on the battery will reverse the transfer! NAPA is just the brand name of s store that sells automotive parts. They have a huge list of suppliers that can furnish parts. If you bring them a condenser with a part # on it, they can source another manufacturer who makes a similar item for you. As long as the capacity and fit is close, it will work!

Thank you to everyone who has responded to my question/s. I will pull down one of the old non working magnetos soon and have a big investigation and go through the steps of replacing the condensor and then having it remagnetised. Hopefully then some of these old maggies I have can live again.

I lashed out today and bought a film capacitor, a whole $1.45 at a local electronics store. I'm not sure if what I bought is going to work or not. It has all the right values 220N which apparently is the same as 0.22uF and has a voltage rating at 630VDC. Its construction is rectangular and made of plastic. This is the part that concerns me. Will the plastic withstand the heat from the engine. I intend to use this capacitor in the flywheel magneto of a Victa lawnmower engine. In future should I look at capacitors that are made from something else.
I still intend to try this capacitor and because of the ease of fitting it and replacing it if neccessary I will have a go!
Looking forward to any and all comments.
Cheers John.

John:

That capacitor should work like a champ. It should be able to withstand the heat, too.

The only real difference between what you've got and the original is that the original is in a tin can and yours is not. This won't have any effect on the capacitor itself.

Take care - Elden
