Always had a problem with my GPS in my KR-2 not operating on aircraft power, 
but ok on internal batteries.  Always made a note to trouble shoot that when I 
got a chance.  Did not need GPS on first flights over the airport.  Today while 
hooking up power for the new flap actuator, I found 2 each AN970-3 fender 
washers on the power control printed circuit board.  One was laying loose on 
top of some components; no problem there, but some bouncing around could create 
some excitement.  The second washer was wedged firmly between a grounded brace 
part of the power panel and the output terminal on the GPS power toggle switch. 
 So, every time GPS power was switched on, the electronic circuit breaker would 
trip and no power for the GPS.  Removed the offending washers and all is well.  
Have no idea how these two big washers got there.  Stuff happens.

So, have possibly toned down the level of excitement for subsequent flights.
