Funny part of this is I am a electrical designer of nuclear submarines (Electric Boat Groton CT)(electronics is a different animal) I spoke with one of the electronics engineers. He mentioned moisture on the wires to sensors. I read a similar (unsolved) problem from a Texas guy on the forum...another highly humid area. Of course little humidity in service areas esp left for 3 days in controlled environment. If and when this is trouble shot right I will let everyone know the answwr....where's the Car Talk Clik and Clak Tappett brothers when u need theml
