It is nice to know that you completed your flight with both mags still working and if one ignition circuit, perhaps fails, d ue to everything under the cowl at high temperatures, it is nice to know. Also if this were perhaps the flight that one ignition circuit fails (more likely to fail engine running than in the hanger), it is better to know now rather than on the ramp wanting to take off per plan. I discovered that in my defective stator coil there were 2 intermittent con nections, right at the rubber 2 conductor connector of my defective stator coil. I am on a mission to find out where the other side charging coil is open. It would be nice to discover that it also has a simple connector wir e problem and not an open within one of the 2 coils that make up the chargi ng circuit. Even after taking extra care to clean all of the contacts (grounds, power . ..) putting everything back together with the new stator coil, my analog ta ch is reading way high.

And it should show as higher EGT's and possibly highe r water temps. Both coils fire at the same time but if one is not working, the cylinder is running essentially with retarded spark. If you did not o bserve this, both systems may have been working and the one failed when you did your test. I must admit, though, that I have never tested the plane i n-flight with one mag only, to see how it acts. If you switch to mag 2, mag 1 is grounded. Mag 1 could fail during the tes t and would show up as failed when you switch to mag 1. If the engine dies on the first mag that is tested, then it was failed during the time of run ning. (I am thinking of the typical 'mag 1 / mag 2 / both / start' switch) Not saying they don't fail in flight, just that it's not the common mode of failure. -----Original Message----- From: Barry J Edwards (BT) Sent: Mon, Aug 19, 2013 10:33 am Subject: Re: Pulsar-List: Re: [Pulsar-Aviators] New Stator Coil In - Flying Again Some years ago, following a 20 mile sea crossing, when I touched down at my home base, I did, as always a mag check and found one mag was not working.

The engine monitor on my 210 has individual sensors on both mags so if either fail when the master switch is on, I get an indication. Prior to getting the engine monitor, I would do a runup and mag check prior to shutdown. I suggest that checking mags in flight is not a good idea.
