You don't do a mag check on things that are not
mags . . . If you've got a coil misbehaving
the engine will let you know about it without
any sort of preflight check.
Bob, I can count on one hand the number of times I've disagreed with
you, but this is wrong and dangerous. I have dual coils on separate
switches, so that I can test each one during a run-up. One uses
mechanical points, and the other electronic points. They are both on
for take-off and landing, but only one for cruise.
- Six months ago, I noticed a 150rpm drop on one coil. Cleaning the
mechanical points cleared it up.
-Three days ago, the engine died when I switched to one of the two.
Turned out to be a blown fuse after I had switched out the coil for
one of the "magnum power" versions that drew more current.
If you've got dual coils, you will never know that one is misbehaving
without the ability to switch the other off.
BTW, I also have two fuel pumps. Both on for take-off and landing,
but run-up includes a check that the engine runs fine with either in solo.
Same thing running a coil joiner with one spark plug. There is no

change in engine performance if one quits.
