Common knowledge is that ignition systems fail on shutdown (possible voltag
e spikes??). Testing pre-shutdown probably won't help, the testing itself
may cause the failure. In my mag check procedure, it's not the RPM drop t
hat's important, it's the return to normal RPM on 'both' that is important.

Pulsar Friends,
Put in the new stator coil in my 582 and ran it through 4 rounds of touch
and goes Sunday evening. Relief ... the Pulsar and I are looking forward t
o the convention.
After this experience, I learned and added a step to my engine shut down pr
ocedure, do a mag check. 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. Fortunately my digital tach is what I reference.
Last time I fixed it, I added a stainless steel external tooth lock washer
on the heavy ground to dig into the metal surfaces and provide a good conne
ction to the engine block (but I cleaned this terminal again and still have
the lock-washer in place.
Looking forward to the convention.

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. It was working when i did the pre take-off check. I ALWAYS
check my mags before shutdown for the very reasons Ron was saying:
better to find out before you leave the airfield, than the next time you
want to fly!

A failed igniton should show up as a reduced performance, ie. more throttle
for the same speed. 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.

Another alternative is to monitor your engine. 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.
