Of course I have never left the master switch on, but I have heard of plenty of folks who have.
I am working on a master minder that looks at buss voltage. If the buss voltage is less than 13v, you can assume the alternator is not putting out. at that time there will be an output to light a low voltage light, and then after a period of time of low voltage, it will have an output to actuate a relay that can turn on the strobes, and or turn on a sonalert or other warning device. This would be installed on a pull type circuit breaker so you don't have a warning blaring at you if your alternator goes kaput in flight.
My question is;
1. is this worthwile?
2. assuming it is worthwile, what should the time between the low voltage warning and the "turn the master off dummy" warning be?
If using this without an enclosure is acceptable, I can see about a $30 cost.
