Thanks Dan & John.
I believe you guys may have nailed it.
With the starter key engaged I get 12v across the master relay.
Disengaged, I was getting 2v. Someone suggested it may be "ghost" voltage, but it may be enough to deactivate my avionics bus.
Dan, I'll try your setup with the master relay diode to ground & see if that resolves the problem.

Default Starter solonoid

Does it matter which large (left or right) terminal you install the battery cable to on the starter solonoid? It works better in my install to connect the battery cable to the right terminal ( small s terminal being left side)
Thank you
Bob

The correct answer is, 'it depends'. Many Starter solenoids (typically ones designed for engines with old Kettering ignitions) have an additional 'small' terminal that may be tied internally to one of the 'fat' terminals. It's intended to bypass the ignition system's 'ballast' resistor during starting. So if you hook up the fat wires backwards, you may have an additional always-hot terminal on the contactor. Not really a problem, as long as you're aware & make sure you don't hook anything else to it.
