Can't say the drop across the switch since I never measured across it.
Neither did I try turning off the transponder, PCAS, and Streak.

I did, however, get behind my panel last week and changed out my master

switch for one more substantial in current capability and have experienced
a

major improvement in function of my equipment. The switch that was

installed when I bought the glider was adequate for the CAI302 and the

MicroAir 760 but, after installing a Trig transponder, a Dell Steak and a

Zaon MRX, all operated from the same bus, the current capacity of the
master

switch was the limiting factor. After two flights with the new master

switch installed it would appear that the problem is solved.

Dan just curious, on the old switch you took out, what was the actual
measured voltage drop caused by the faulty switch. Also did you happen to
measure the resistance with an Ohm meter? I had a similar voltage drop when
I used a riv nut to make a terminal post on a battery. Ironically it was a
new LiFePo4 that didn't have the typical attachment connector. FYI I have a
master switch and use the First On Last Off sequence that JJ referenced.
