I think I have the OAT and voltage issues corrected via setup procedures....offset adjustments
System says the magnetometer is not connected...jeez. Connectors are firmly connected. 4500 to molex at pilot's left foot to magnetometer. Need to meter out next time to try to narrow down.
Aerotronics did the connection in the db-25 at the 4500 and did the 9 pin dsub at the mag. end. I did the molex, so that is where I will look first. Some discrepancies in wire colors for Aerontronics to AFS diagrams. Aerotronics has 2 blue-white wires. AFS shows BW, OW, GW and 2 whites. Maybe I reversed the two BL-WH wires? Maybe bad pin connections although I have not had much trouble with pins
