Default Oil Burner Ignition Coils

Long story short; I have a Webasto 12v fuel oil burner. It has a 12v coil that goes to 2 electrodes. Mine died, a new one is $500...yes, $500 for a coil.

Question is, how can I improvise? After all, a coil is a coil....yea?

You might get away with a K&W model T coil. They put out about 40,000 volts compared to the 15 to 20000 a ford coil puts out. The spark has to be really hot to light fuel oil. You don't want to get bit by a K&W coil either! It all depends on what the controls put out to the coil, and if the resistance and power demand meet the burner's needs. Have you tried an on-line source for parts?

Once, when the ignitor transformer in our oil furnace went belly-up (on the coldest Saturday of the winter, (natch); I rigged an old neon sign transformer to do the job. It worked like a champ.

That was good because it took a couple of weeks to get a replacement.

Oh yeah, I can find the coil, but I'm not paying $500 give or take.

This s what I came up with to replace a very expensive igniter for a Karcher diesel powered pressure cleaner. Using a car ignition coil. The Karcher & the ign coil & switching transistor all came free from local Scrap yard, is a great machine now.
