Permanently installed the Batt & Master contactors. It's hard to see the connections but basically, the two contactors are connected via 2 copper straps per print. Then another strap jumpers to the top ANL base and then another one goes down to the second ANL base. All of the copper straps are covered in a double layer of heat shrink insulation, because once you hit that master switch, them and the Batt positive cable (yet to be fabricated) are pretty much the only unfused items on the airplane, and I have no intention of just having bare copper hanging out in the breeze. The idea is that the starboard side of the top ANL will feed the fat wire going into the cabin breakers and the bottom one will carry the output from the alternator back into the system. This is a common setup and anticipates the two most catastrophic failure modes; 1- a short in the fat wire into the cabin 2- a failed diode in the alternator that causes it to shove beaucoup amps into the poor electrical system.
