Thank you sir. We had many issues with them from an electricians standpoint but aside from the one I had already highlighted was called the SDC (Signal Data Converter) which sent a signal from the tank probes to the indicators. Whoever thought these up was definitely a bookworm with no real life experience. We would adjust these things for correct indications only to have them knocked off by vibration because the adjustment potentiometers were not the locking type. The enlisted mans solution........ Run a bead of torque seal over the adjustment point so the bastard wouldn't move. That would last for maybe 2 flights and they'd be back 4-5 at a time. I had always loved the tomcat since I was a kid, then I worked on them lol. But still that little piece of me retains that. Who wouldn't?
