The heart of the electrical system is the VPX PRO so there are no regular circuit breakers anywhere in the aircraft. There was a steep learning curve, at least for me, in learning how to set it up, but once I got the hang of it, it was pretty straight forward. Stein Air sold me all of my avionics and designed my wiring diagram. I can't say enough good things about this company and would HIGHLY recommend them! They drew out my wiring diagram for me and even printed it in full scale. I referenced that sheet many times and would still be wiring today if it weren't for them. I used their main wiring that Van's sells and I also asked them(Stein) to make a small harness to connect all the garmin products. The harness was flawless and saved me month's. I used a grounding block with many tabs (48 I think) believing this was overkill, however I still needed a few extra. The alternator is a 60 amp Plane Power that comes with the standard engine. I used a B&C 40 amp back up alternator attached to the accessory case. I removed the old fashioned magnetos and am using P-Mags instead. There is simply no comparison and not one reason where the Slicks had an advantage. I have a single battery(Odyssey) system even with P-Mags because of their self generating internal alternator that is the primary power source. I did install an IBBS back up battery for the avionics which can also substitute as a battery back up if both the primary E-Mag alternator and main battery both fail (extremely unlikely). I have installed a split, cessna type, master switch, an avionics master and a start master. The starter buttons are on each of the Tosten Stick Grips. If you have ever had to restart a dead engine with the prop stopped, you will completely understand why you want a start button on the grip (I've done it twice).
