Does anyone have a wiring diagram or installation manual for a Collins 331H-3G CDI? I'm connecting it to an SL30 and having a little trouble. The flags are working and I have the OBS rotor communicating both ways but, my needles aren't showing any deflection L/R or Up/Down. I've got L/R on J and K and Up/Down on M and L. I appreciate any help.PXL_20230821_214724995~2.jpgPXL_20230821_214734783~2.jpg

Thanks, I found that thread as well but, it didn't really have what I was looking for. I managed to find a manual, attached is a copy in case anyone else needs it in the future. The resistance readings for the coils and some of the other troubleshooting proved helpful and I finally managed to get it working yesterday after redoing a couple of bad crimps and moving a few pins around.
