I Am nuts for aeroplanes
On initial power up, all six readings are same as OAT. If I turn on strobe lights, they all immediately go to -99. Turning off strobes doesn't help, but recycle power to EMS fixes it. Totally separating strobe wiring from all other harnesses and trying again does not help. On a few occasions, flexing the wire harnesses also gives me -99. Is there a common thread that would cause ALL indications to go -99? Such as an interrupted ground? Nothing is noted on VMtr or AMMtr like a power surge or ??. Help??
