Magneto Question

Postby clodhopper » Fri Sep 28, 2012 11:55 am

My Betty Lou ('50 Demo) was equipped with a magneto ignition. At some point someone added an external. Now I know its cheaper to replace a 6 volt coil, but i want to put her back to a magneto. The cover was broken on one corner. I am repairing that with JB weld. My question is this...the coil is missing, but there seems to be a coil core (#11) That I dont have. Anyone have a source for these parts that is not completely out of reach? The cover alone ive found is $70 dollars. Thats why I am repairing mine. I was just curious.

Paul, I don't think that TM has the parts he's asking for. Ed

I have another question. What exactly is connected to the terminal inside the coil cover that goes to the center wire? Looking at the.coil, im assuming the lead, which has a ring terminal, goes to the stud and is connected to the kill switch. How is the spark getti.g from the coil to the terminal?

The coil is made with a small copper "nub" that contacts the terminal strip inside the $70 cover. And those coil cores are awfully hard to come by. You have to rob one from a magneto, I don't know of any source for those, and they look a bit difficult to make correctly. It's a shame, but many probably went missing when the owner added an external coil.
