                    Dual batteries, dual master switches through dual solenoids.  alternator switch, Standard alternator  checked every 100 hours,  spade fuses on everything.  Basic and definitely not flash.  Same old story, how far can you go with backup?  You have one prop, one engine, one rad , one set of hoses, one ecu, etc.  Just review where you fly as without insurance, I do not want to land in a preschool and live!  These days it is just "insurance" to fly and take the train for the final bit.

Hi Guys

I’m reviewing our electrical system and thought as its a critical system i should get the wisdom of what other decided as far as risk.
If people have circuit diagrams that would help.
I have an electronics background.

My key questions are around:

Battery/s (single/dual) If dual - how have you implemented?
Alternator (Capacity to control - Over Voltage etc.)
Switching (How you switch the electrons on/off - I recently had a Narva Ignition switch failure)
Failure modes and emergency response plans

Much appreciated.
