***** Thanks Paul C, and all who took the time to give me their views. Just
about everyone uses a seperate starter button.    DMcC

Since everyone is doing it that way, I will admit that I did it differently.

I bought a gerneric 4-positions key swithch for $10 a the auto parts store. With "accessories" I turn on the EC2.  "run" gives me the EC2 and the primary fuel pump.  "start" gives me those as well as the main starter relay.  This relay has only a small load on it so it is unlikely to fry the switch.

My main starter relay only has 2 jobs - trigger 2 other relays.  One of these is the starter solenoid, and the other is a cross-over relay that allows both batteries to be used for starting the engine.  This way the cheap starter switch is protected from the back current when the solenoid closes.

The main advantage of this system is that the starter is locked with a key.  Helpful for airshows and assorted accidents.
