Default 12V to 6V stepdowns

Ok, I get it. It looks like it is better to run these old igniters on 6V. Where can you get a risister to step 12V down to 6V. I built this nice inition box which contains a garden tractor battery and it all fits nicely. I would like to use that set up with the new primary coil I've ordered. Is there a way , and a resister available that will do that?

Go to your local automotive store. and ask for a resistor for an old mopar
car they come in different resistance. they are ceramic with internal resistor. might have to run two to get 6 volts.

It may cut it down to 3 volts

Walt:

What I do is just hook a 12 volt brake light bulb in series with the battery and coil. It doubles as an indicator to tell you that the ignitor is working.

I use it all the time on my F-M Jack of All Trades with the original coil and a 12 volt gel-cell.

Take care - Elden

Thanks , Elden. I knew some one out there had a simple solution. What a great idea to indicate the igniter is working.
