cessna 180 O-470R

mag went dead the other day in flight, when i turn it to "R" the engine quits, so does this mean that the right mag is dead? i been getting a few conflicting reports from guys on the field about this, some are saying my left mag is dead, not my right

If the switch is on R, and the engine quits, the Right magneto has a problem. Or your ignition switch does.

Points, condenser, capacitor, P-lead interface, nylon distributor gear; All could be a trouble item that could render a mag dead. I'm experiencing this very fun right now too!

ok, thats what one of my mechanics said, so looks like i need a 6310 slick rather then 2380 lol

i have a good feeling its my mag, its gone though quite a few hours

Make sure you check that the leads going to the mag are indeed on the correct mag. Its a PIA to find out you changed the wrong mag because somebody didnt bother to hook up the p-leads correctly.

Good call.

I've just recently remedied magneto trouble with a lot of good help. I would recommend you contact Aircraft Magneto Service, Boeing Field, Seattle. They were extremely helpful to me in troubleshooting my Bendix 1200's , although they're well versed in everything else. Their background is aircraft accessories so they can tell you what else might be the trouble if it's not the mags. They have a troubleshooting guide published on their website called 'Is it the Mag?' The guide is listed in the sidebar. You'll find their website at http://www.aircraftmagnetoservice.net/

IF it were me, I would consider disconnecting the right mag p lead at the magneto. Start the engine and check the mags.
If the engine still quits in the Right position, you have eliminated a grounded p lead or ignition switch as the problem.
That would be the easiest check.

If it still quits, I would then pull the magneto.

Good luck

Ditto the recommendation on making sure the p-lead isn't the problem. This is a pretty common thing to happen.
