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.

This probably sounds really stupid,  so I'll ask anyway!!!  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.

 There should be an "F" designating which terminal is the Field connection, 
normally .
