New PA-18 Project in Louisiana

Here is revision B. Using switching circuit breakers (I might need one more for the generator, not certain yet). I plan on using an ipad with wifi link to the Stratus 3i. There should be enough space to mount the tablet. Considering Denny's advice about moving the switches for rev C, maybe. Appreciate all the good advice. IMG_20240604_205439250.webp

The starter button seems like it’s in an odd spot. If it were my plane I think I’d want the starter button on the lower left, in the region where the mixture is marked. That way I could mash the starter with my left hand and pump the primer with the right hand (if more priming was needed).
 
Speedo, I like to have my left hand on the throttle when pressing the start button. It is just what I have always done. Not to say it wont happen, but it is rare enough that I will have to get out of my comfort zone to pump the primer while starting an engine.
 
Here is my wiring diagram. I did not run a redundant power like the original wiring diagram shows. Any issues with that?
Something seems a little off with your wiring diagram. I am going off memory but doesn’t there need to be a CB on the field relay for the generator? Also why is there two 5 amp CB’s on the master relay?

I really like your panel layout!

Thanks Charlie. The wiring diagram in the Owner's Handbook does not show a CB in the Field circuit (if I am reading it right). I put fuses in the master switching circuit to protect from short circuits, since one wire is always hot, and the other is hot whenever the master is on. And because they run quite a ways through the airframe.

You are correct on no CB for the alternator field. Most of the Cessna’s and I think later model Piper’s typically have a 5 amp alternator field CB. I don’t recall ever seeing a CB or a fuse in the master relay wiring digram on anything I’ve worked on. I just checked the Cessna 172 wiring diagram and it didn’t have any.

If you look at a later model PA-18 wiring diagram it doesn’t have CB’s protecting the master relay either.

Not saying what you’re doing is wrong. It’s just not normally done. I am not sure of the reason for that.
