[simpits-tech] Tech Help Needed: Aircraft Power

[Rod Dale]

Roy,
I agree with Darren - look up the wiring diagrams and manually trip the 
circuit breakers. That's one of the reasons they are manually "tripable" so 
you can isolate systems from the power busses. And keep the "amateurs" away 
from the electrics :-)
