I have an RV-4 I built with all steam gauges, and recently, I took the leap to a G5 for my primary centered instrument but retained all my other steam stuff for now. I never had a AF Horizon, and now the G5 has me all set. Since the G5 is often used as a back-up, power source seems to be best coming from the main bus the way I see it, and in the event my AVX (com,xpndr,ect) becomes a smoke generator, I want them off-line(AVX bus). Being all that said, I have the G5 wired to the aircraft master side of power, which means the G5 comes alive with the master prior to start of the engine, and I am curious if anyone has had issues that would damage the G5 due to voltage drop and drain during engine crank? I really don't want to physically turn on/off the G5 with every flight cycle. The install manual isn't very clear on preferred/recommended or precautionary choices. How are others wiring theirs?
