I recently purchased a Sandel 3308 EHSI system from a member here. The remote gyro included is a Bendix/King KG102A and the magnetic flux detector is the subject CT-504A. The Sandel installation schematics include the KG102 gyro info but pair it with the Bendix KMT112 flux valve. I'm trying to sort out the difference, if any, between the inputs/outputs of the two flux valves. There's schematic info available on the KMT112 but so far I can't find anything on the CT-504A other than the input/output diagram on the side of the unit. Both have 5 pins, but need to make sure which inputs/outputs are which. I'm going to do a web search and get contact info on the manufacturer, Humphrey, Inc. San Diego, if they are still around. There's also an Aircraft Radio and Control (ARC), i.e. Cessna, label on it and also an Edo-Aire Mitchell p/n... If anyone has a schematic for a CT-504A ARC p/n 44770-0000 (I don't have the other p/n's with me at the moment) they can share I'd be much obliged.
