The Rotax cylinders are a nickel silicone combination called Gilnasil its a process
that is done by many companies.... all based on a matrix of nickel with
small particles of silicon-carbide.

the manual says to remove the top plugs and turn over engine to purge oil system.
what it doesn't say is do you have to protect the coil by leaving the resistor
wires connected to plugs and leave them grounded out to cylinder jugs. or
.. just let leads dangle and plugs on the bench. i understand the mags will be
off when swinging prop but is there potential for damage to ignition

The danger to the ignition is only when it is live and a plug is ungrounded.
There's a diode in the module that will fry if you do this, which is why
you're taught to use an ignition spark tester between plug wire and plug to
check for spark. When the ignition is off, as you put it, the mag is
grounded, hence no problem.
You are doing the purge turning the engine over by hand, aren't you?
