I just acquired a Shadow and the lower backbox GI wasn’t working. I measured the voltage across pins 3 and 9 on J120 and got 1.5 volts. I measured the voltage at J115 and got 1.5 Volts on several wires.
I then moved to the GI transformer plug to test voltages and as soon as I picked up the plug, the lower backbox GI flickered, then came on perfectly bright. As I gently wiggled the wires on the transformer side of the plug, the GI lower backbox GI would come on and go off. None of the other GI is affected.
Has anyone had to rebuild this plug? First time I’ve had an issue with this plug in probably 30+ DCS games I’ve owned.
