Does anyone know the wiring scheme for the Yaesu FT107 dummy plug? This is the plug that is inserted in the DC power socket when the AC supply is to be used. I couldn't find anything online with reference to it.

Tnx,

For things like this, I like to increase my chances of getting the information I
need by posting in other relevant groups, too. These would seem to be other good
places to join and post:



/g/Amateur-repairs

and maybe check mods.dk to see if a manual is available there that has the
schematic for that. You can only download one document per day for free from
there but sometimes it's the only place to find old manuals.

I have the manual. It just doesn't discuss how this plug is wired. I suspect it's pretty simple, because there is only a plus and minus contacts. Thanks for the other suggestions.

Perhaps someone in the other groups I linked to can help.

I finally figured it out after studying the schematic for the power supply and the rig. Looks like pins 1&3 are connected when using the internal ac supply.
