Schinderhannes Posted January 2, 2023 Report Posted January 2, 2023 Unfortunately Mid-Continent took down the wiring diagrams for the MD40 series indicators. Does anybody have the wiring diagram / pin layout for the MD40-242 indicator? This is the indicator for GNC300/GPS155. Thank you, Frank Quote

It seems that if you were clever you could figure out the pinout with a meter and a power supply. You might look in the install manual for the navigator it hooks to. Quote
Schinderhannes Posted January 2, 2023 Author Report Posted January 2, 2023 Thank you Rich - I have the MD40 general refences and L/R & From/TO are standard on all MD40 indicators. The tricky part is the wiring of the resolver. I had wired it following the MD40-232 diagram in the hope it would be the same, but it didn't work. Hopefully somebody has the -242 diagram. 1 Quote
