There is currently a discussion here:I am working on a Fairbanks Morse Z, 1 1/2 hp, open flywheel but I lack the AB 33 magneto. I've seen videos of the engines running without the mag using a battery and coil and perhaps a micro switch. How is this set up? Any help would be greatly appreciated.
Yes, but your micro switch must be able to handle the current draw of the buzz coil AND deal with the DC arcing as the contact breaks... Maybe use a relay controlled by the micro switch or just make a friction contact with plenty of contact area which is easily cleaned:shrug:Thanks. My latest idea is to build a bracket and attach a long levered micro switch in combo with mag and buzz coil. Does this make sense?
