Chain Counter Display Wires

Happy Holidays to all,

Thomas Peacock on SM #240 Aletes did a nice writeup on the Chain Counter Wiring here:

However, SM 466 seems to be a little different.  I have 13.2 volts on the Brown wire at 11 o’clock on the rear of the display unit (see photo), but I have lost power on the Brown wire at 7 o’clock (had it yesterday).  There is writing on the outer insulation on both of these, but I can’t make it out.  I had power here yesterday (I believe 12.5 V but it could have been 24 V), but while tinkering around up there with the chain counter wires and the voltmeter, I think I may have shorted something and blown a fuse.  But I don’t know where to look.

I believe the source of power for the wires at 11 o’clock is the 24v-12v converter under the Nav Station, but I am not sure - I do have power at the converter.  I have no idea the power source for the wires at 7 o’clock.

Is there anyone in Amel Land that can offer some insight here?

Thanking you in advance for any and all assistance.

All the best,
