@Lister: do Icom have an address in the UK? Would they even have one on the continent?
@Andrew: the documentation says nothing about an integrated charger, I do not think there is one, though there might be. I was thinking of testing with the classical setup of an 7809 or 7810, boosted with a PNP transistor and perhaps adding some kind of current limiter for short-circuit protection. Plus if I'm really courageous an overvoltage protection on the output, for the day the 7809 renders up the spirit.
Think the 7810 might not be really happy even with 13V input so my first idea is a boosted 7809. But I hoped for some confirmation such a setup cannot damage anything inside the A6E. It's bad and stupid enough I blew up the adapter, don't want to go any further that path...
PS I'm flying a Coyote too: OO-F75 (club-owned).
