A small correction to Larry's post above.
Pete Somers in the UK was our chief electrical/electronic guru and he indeed passed away this year. He was always quick to answer queries like this one and was equally quick to accept my invitation to be our guest speaker at the 2007 Annual Fly-in in Lucaya, Grand Bahama Island, where he enlightened us on these topics.
But I'm reasonably certain that he is not the Peter that created and ran the original Skymaster web site, because years earlier I collaborated with him on some of the web pages (e.g.,
www.skymaster.org.uk/purchase.asp).
Both were named Peter, both were from the UK, but they weren't the same bloke.
That original Skymaster web site still exists and the message board archives may be found at
www.skymaster.org.uk/mba.asp but while some of the archives are there (e.g., Engines), others are missing, including the Airframe messages that cover electrical/electronic issues.
