My ignition system consists of dual MSD boxes,one fed
throught the main buss and the other fed straight from the battery. I
run a Optima gel cell unit that has 950 cca and can deliver enough
voltage to run the ign for hours. The DAR that inspected my plane asked
that very question and together we calculed I would have to land three
times for fuel before the ign would fail from low voltage. I would like
to think I am not dumb enough to take off the second time in that
failure mode. G

Your ignition that is "fed straight from the battery." is it straight or do
you have a high current isolation diode in there (and hopefully fused!)?
If not it could fail and take down the battery/alternator and main buss
also.

Just curious, no flames ;-)
