Originally when I built the electrical system, I was of a mind that an avionics master switch is a single point of failure and should be avoided. \u00a0I have since changed my mind. \u00a0First, \u00a0my comm2 radio has no off switch (MGL V6), second, I really want my comm and audio panel volume settings to be set and left alone. \u00a0 Third, and this is the most important thing, I want to minimize the danger of transient voltage spikes damaging very expensive equipment when starting and shutting down the engine.<\/p>\n
The simple fix is adding an avionics fuse block\u00a0inline with the Endurance bus with a switch in between. \u00a0 The EFIS has its own power switch and will remain on the E-bus. \u00a0So far so good, and the install went smoothly, except for the time I dropped the passenger stick through-bolt down the hole between the center section ribs. \u00a0That was fun, because my fat hand doesn’t fit past the stick through the access hole, and I wasn’t about to take the floor panel off. \u00a0 I then fished around with a magnetic screwdriver bit holder, and that sort of worked, but then somehow, I dropped that in there too. \u00a0 After a brief bit of grumbling (seriously, how long can you stay mad being at an airport), I was able to fish that out of there with a couple of long aircraft drill bits held like chopsticks. \u00a0 After that, I got my bolt back.<\/p>\n
I forgot to bring little zip-ties to re-secure the DB25 connector on the pax stick. \u00a0Also, I forgot to bring my little screwdriver so I could tighten up the connector on the back of COMM 2, which will get fixed tomorrow morning before work.<\/p>\n
So now I’m less worried about blowing up my avionics than I was. \u00a0But the process was suspiciously painless, right up until that last bit.<\/p>\n","protected":false},"excerpt":{"rendered":"
