Magnetos switch for 7AC

Post by pablo »

Apparently my Magneto Switch age's beginning to show. Any suggestions about where to find a replacement in good condition?

If you have the A-7 or A-9 can be cleaned up to make them look real good And usually you can remove the back and clean the contacts and you back up and running.

Give it a try or replace it with a used one from Ebay for $$$.$$

While we're on this subject, a week or so ago a friend of mine was pulling his prop through with the switch off to prime it and it fired :shock: . No harm done but only shows it's best to treat it like a loaded gun. Interestingly, it shut the engine off before and after so I suspect the contact points are probably dirty or corroded also. Only takes once!!

If you think you can rebuild the Mag switch then get a hold of the Oct 2003 issue of Vintage Airplane, the EAA Vintage club magazine. It has an article on how to rebuild these switches.
I think it was originaly published in the Cub Club News by Steve Krog and Bob Gehring.

A couple of years ago, a friend asked me to prop his J3 for him. He said to pull it through 6 times with switch off to prime it. He verified switch was off, brakes on. On pull number 3, it started. It was such a surprise, that I was almost in denial and wanted to reach out and stop it. Fortunately, I've always treated every "pull through" as though a prop is hot, even when priming. Friend was in shock and assuring me switch was off. Turned out to be a loose P lead. Never assume when fooling with a prop. It does happen.
