Scott, I gave this a lot of thought while building and concluded(after frying one relay in testing) that their diagram might be the safest alternative (even with the potential to burn up relays). I decided that with main pump power coming straight from the battery, it was wise to leave control power switched. This motivation was to prevent an accidental gear up on the hangar floor from the gear system still being powered with the master switch off. I guess the final perfect fix has a separate relay and or big amp switch for the whole system? Anyway you see why I would arrive at the conclusion to leave it alone. Save a switch, relay, save a lot of wire, gain a 1/4 kt in weight savings, and save a few brain cells (the last of which were spent wiring my Control stick Koolie hat dual axis trim relays). As it stands in my plane control power can be turned off after pulling the 50 amp breaker(thus saving the relay) by selecting my Essential bus and turning off the Main bus. Adding a little detail clarifying the pros and cons of this action in my abnormal checklists would be prudent. On the other topic of the "In-Use" light having high amperage dangers. I agree totally. I'll now have to add my third inline fuse to my electrical system. Thanks for the heads up! In my copy of Websters electraulic is not a word. Therefore, it will have to remain a fine sniglet for the time being. Keep the pressure on, I hear they make changes every year. Larry Henney N360LH
