Okay, thanks . . . is there a recommended system
wiring diagram I can access?

Un impeachable logic: George Carlin asked, "If black boxes
survive crashes, why don't they make the whole airplane
out of that stuff?"

If that 40 amp fuse blows, the engine quits. Remove it.
Repurpose that 40 amp fuse to protect the electrical system from a shorted
alternator or its "B" lead. Or use a fuselink.
Good workmanship will prevent the engine busbar from shorting out.
Relocate the engine Fuses. They should be between the busbar and the switches.
The 60 amp fuse is not needed. Eliminate it.
I suggest that you use battery contactor in series with the aircraft main power
bus
(not to be confused with the engine bus).
There should be a fuse between the engine busbar and the start push button.
