Hi Guys,

Anyone have info on how to stop the 447? Do you ground something in the ignition circuit? What's normally done?

Thanks!

Hello

It a normal. Motor has made for running in flying even with open circuit for safety.
while open circuit, motor continues running.
Like a sea boat of Kill Switch, by making short the motor stop.

Brother cdupuis...

Bet you had a fun time with that name in high school, eh...? Beauford was
nearly as bad, I reckon...

Anyway, the 447 kill switch ("shorting cable") wire is black and yellow...
Ungrounded is the "run" condition, ground it to
kill it.

Getting mine to stop running has never been the problem.... Good luck with
yours...

Worth what ye paid fer it...

Sir,

To kill the 477 simply short the Black wire to the Yellow... I do this with a toggle switch. In fact two toggle switches wired in series. That way the engine will happily run with both switches open, or one switch open and one switch closed. Both switches must be closed to kill the engine.

This set up is a safety feature. Saved my bacon on my first solo, when I inadvertently hit one of the switches to the closed position while in the air and the engine kept running. Unless you have an electric starter getting the 477 lit again while strapped to the seat can be problematic.

Attached is a simple drawing of two toggle switches in series...

Good luck.

Aloha,

Sir,

I believe I mis-spoke in my last post. I said to "short the black wire to the yellow"... I should have said (and drawn)"short the black & yellow wire from the engine to ground". My ground wire runs back to the engine case.

I am on the mainland now, so I'm about 2,500 mile away from my plane and giving you advise from my aged and faulty memory... Sorry.

Now you know why I wish you good luck.

Aloha,

Henry

Thanks for the info! Much appreciated. Drawings need to be fleshed out a bit.
