Not true! The advance and retard have nothing to do with how low the voltage is and if you have enough voltage to turn the starter there is more than enough to power the LSE. LSE will work to below 6V. The Sky Tec is known to draw huge amounts of current.

oh ok then. You better contact skytec and tell them their tech is wrong.

anyway, I dont really care because things are working the way they should and I'll be starting it off the right mag as he suggested because it works fine that way too.

I'm sure the LSE's will fire down to ~6V, but it doesn't mean they always fire at the correct time with the first pass of any given magnet past a sensor. My IO-360-A with dual LSEII's and flywheel trigger has backfired a few times, immediately when engaging the starter. Hasn't broken my Skytec LS starter yet, but my starting procedure now is to start cranking with the ignition OFF and once the prop makes a revolution or two, then turn on the ignition. Never get a backfire that way, and still starts almost immediately.

On previous units working with the high current draw Skytec, the prop would stop after passing the first trigger and it would back up and pass this trigger again which gave the spark. To correct this when Skytec starters are used a fast reset was installed so that the second trigger at -45? appeared as the first as it should be. Klaus had to do a lot of analysis to find out what was happening. It's interesting that a Skytec technician knows all about the LSE ignition.
