Dave, I can not answer your question directly, but I did have the same problem.
I recommend you put a lock (key or cover) on your master power switch prevent it from turning off while the engine/alternator is running. When the turn off master when the alternator is generating you get a voltage surge that can kills devices, even if there is a cb/fuse between them. Same happened to me. I fried two pwr supplies/cords for handheld gps that way. 1st of all never kill the master while devices are running on the alternator. Second, do something to prevent the master from turning off (even accidentally). If you feel the need to turn off the alternator while running, turn off all other devices 1st. I looked at surge suppression devices, but didn't like the prices. I do have a wiring diagram of my system. It is in the POH on my web page.

I have a Revmaster 2100 with the standard alternator, 2 wires leaving from it, going to a connector that has a couple of pins jumped and then to the voltage regulator, etc. For lack of a diagram, I installed a relay between alternator output and load. On a test run, I killed the master switch, but the panel didn't completely shutdown. Upon investigation, I discovered that the alternator was powering the panel, and it cost me a radio in the process. Hence, the relay. However, I think the accepted practice is to switch the field instead of using a relay on the output. So the really stupid question is "How do I ID the field?" Is it that jumper on the connector at the voltage regulator? Thanks! Dave.
