Does the mag need battery voltage to work or is it self energized.

Molinegb is talking about the Wico XB battery distributor. It has a fibre board resistor on one side with connection for battery wire. Yes magnetos produce their own power hence the name. There were Wico XH and C magnetos and other brand magnetos. You should NEVER should have battery voltage connected to a magneto as it will fry the coil, condenser, points and possibly ruin the magnet. The terminal you see on a magneto is for a ground kill switch only.

I had a 39 MM U that had a Wico mag on it. It turned out it was a distributor that looked like a mag. It required voltage supply.

John,
Magnetos do not need battery voltage to function. They create their own electricity for spark. The only wire to a magneto is a kill wire to shut off the engine.

There were some distributors made that look similar to magnetos but it is unlikely that you have a distributor.

Magnetos generate their own electrical current.
