I have a fuji BT-50SA gas engine and it has an Automatic Timing Module run ignition. It has a metal plug sticking out of it but no wires or switch, how do i get one and what do I use. Do i need a battery or is it a magneto run engine? Thanks
Steve

The metal spade is what you wire your kill switch to. If the switch is open the engine will run. If the switch is closed. the engine will not run. The other side of the kill switch connects to the metal of the crankcase.

The engine has magneto ignition and does not require a battery to run. It will run on it's own without anything connected to the ignition. If you connect the spade to the engine block electrically, the ignition will not work.

Enjoy,

The Fuji's have magneto ignition

I asume this is the connector you are referring to:

If I recall, when this terminal is grounded to the engine case, the ignition is off (no spark).

If the terminal is left disconnected, the ignition is ON

I looked at the manual on the fuji website. No mention of the ignition connection.

Wire from the spade terminal to switch and wire back to crankcase ground.

Thanks both you guys, but where do i find one of those kool metal toggle switches and wires to do this with. And i won't need a batery? Thats good one less thing to charge, am i right? Thanks again. ooh, and where should i place these things on my plane and motor?

No battery needed.

As for the switch, that is wide open. You do want to keep the wires for this as far from any radio components as possible.

Go to Rodio Shack. Get a slide switch, not a toggle switch. Get wire there too. Mount it as far forward as possible. Toggle switch will fall apart from vibration eventually.

Thanks a lot guys, i have one more question though, how do i connect the wire to the ignition box. There is a single piece of metal sticking out of it, do i put both the neg. and pos. wire ends on it or do i ground one to the engine and put one on the metal connection, thats something i really need to know, and thanks again
