I have two snags on the C130... in C-130 Technical Posted July 3, 2014 If you have a GTF-6 or silver suitcase available, connect it to one of the flight deck indicators. Follow the tech data to input the capacitance amount for zero and full and adjust the indicator accordingly. Now set in a capacitance amount equal to half full. Check the indicator. Keep changing capacitance values and checking the indicator. If the indicator doesn't follow, you know your indicator is bad. If it does, start looking for bad splices usually in the flap well area. Ensure the splices are environmental. I have changed many splices in the flap well area because the splices were non-environmental and became corroded. Of course, changing out the cable from one coax pass through connector to another is the best choice. Also look at the coax pass through connectors in the flap well area. Make sure the connectors and connections are good and especially checking that the connectors have the insulation washer inside. If they don't, that's an easy way for fluid to enter and create corrosion issues as well. Hope you get if figured out.
