A&P here aswell which is why i think it's prudent to have a properly designed system.
i was planning to have the starter power lead direct to battery and just the starter solenoid/relay is switched by the button and key and master relay, however i could see an inadvertent arc coudl take place spinning engine and blades..
i would be concerned with the starter amperage/current draw damaging the master relay however. the relay i am planning to use is only 100amp continuous latching.
i went with latching because it requires no power to hold its on state, only momentary power to change states from on to off. if a sudden voltage spike/drop occurs i didnt want the master relay to drop out, further spiking the alternator and remaining electrical system.
