I am finally moving forward on my electrical and basic avionics project.

Plane already has a starter, battery and master switch.

Plan is to add a EFIS which will drive a remote transponder. Also; add a radio which will replace the handheld.

Since powerpoint was handy - I just drew a basic diagram to validate the plan. Looks pretty simple but want to make sure that I have not missed anything big.

Feedback is welcome - Alternator is plane and power with OV protection; MINI EFIS and Trig 22 Remote transponder. Everything in green and blue is already in the plane - I will be adding the remaining items in red.

It is better to have separate circuit protection for EFIS and Radio so that both are not lost at once.
That is not really 18awg wire connected to the 60 amp breaker is it?

Misprint on the alternator wire. It would be 4 AWG. I will look into using a separate CB for the two instruments.
