Two wires for +14V IN and GND are for redundancy. Rather
common in avionics boxes. I'm afraid lack thereof will not
solve the orig complaint. In plastic airplanes, the
radiated field is a strong, vigorous one, easily affecting
other electrical items. In aluminum planes, those affected
items are significantly shielded by the airframe. I know
this from me little handy field strength meter, while
xmitting, with the meter inside my aluminum plane, vs.
sticking it out the window in better line-of-sight from the
xmitting antenna. It's needle can peg with a resounding
click!
I'd first try the ferrite suppressors to trap the EMI
radiated to wiring of affected devices. Those things abound
everywhere these days from wall-brick "switching power
supplies" to charge the battery in consumer devices, through
those now found on the RF cable feeding digital, high-def TV
sets or digital cable boxes.
