We have a solution to the "Hobbs on only when engine is running" problem.
We installed a Cessna split red master switch (comforting for a long-time
Cessna driver!) with just the Hobbs wired to the left side and everything
else to the right side. In normal flight operation (as in a Cessna), you
turn both halves of the split switch on and off together. But if, for
example, you want to work on panel electrics with the engine off, you just
turn on the right side of the master switch, and the Hobbs is off.
One more thing we did, which turned out to be useful. (I wish I could
claim thoughtful foresight, but . . . .) We installed a 4-position
ignition switch (off/L/R/both) and a separate push-button start switch,
instead of a 5-position (including start) ignition switch; the 4-position
switch was MUCH cheaper. This means we can run the starter motor to turn
the prop without starting the engine by using the start switch with the
ignition switch off. We sometimes want to do this for test purposes, or
to turn the prop a few revolutions on a cold day (to get the Rotax
"gurgle") to check the oil level before the actual start.
