I need to handle 2 axis trim, speed brakes, and CWS. I've published a drawing at: http://www.aeroelectric.com/articles/Pilot_Priority.pdf The upper drawing shows how to wire control stick grip switches for automatic/manual override of the copilot's switches by the pilot. The relay is used to disconnect the copilot's switches any time a pilot's switch is depressed. The toggle switch selects full-time or automatic disable of the copilot's switches. The lower drawing is a bit simpler. It has only a manual disable switch. This circuit does not allow pilot override of any single switch . . . only a choice of whether or not the copilot's stick controls are active.

I'm wired per your diagrams for dual battery, single (internally regulated) alternator. I'm considering adding a wire from #2 battery buss via a switch to the E buss. This way I'll be able to power my essentials (EFI computers, Fuel pumps, Injectors, Coils) from either battery without using the contactors. Any reasons why this would be a bad idea?

That works . . . but are you not confident in your ability to maintain batteries such that you KNOW be for you fly what endurance can be expected from each when and if the alternator quits?

Just yanking your chain my friend. That's an excellent idea that promises to produce irrefutable numbers that can only build your confidence in a system you depend on and increase the value of your advice to folks considering similar systems.

Just as with fuel - I'd hate to run out of accessible amps while still having some on board. I could run one pump, coil set, and injector set of each battery buss, or I could run them all from the e-buss and switch the batteries. I prefer the latter since the EC2 computer has (effectively) only one supply lead. I guess my confidence in batteries has weakened recently since I managed to fry three with two different chargers in the space of a month. One, a so-called "smart" trickle charger and the other a conventional 6 amp unit. In the second case the battery was HOT, smelling of acid and bulging at the seems after an overnight charge. :( Perhaps a lesson on charging these rg batteries is in order.....

Does anyone have a source for starved lead acid batteries in the UK, and in the Philippines? I'm looking for 20 AH to 40 AH screw terminal 12V. They *don't* have to be bargains, the company is paying for them, but I really, really don't want to try to take them over in my luggage.
