DZ126IN blue wire
« on: July 07, 2019, 06:44:06 PM »

I know I was able to find this before, I swear it was even on here, but I cannot find any reference to a pad on a DZ126IN where you can solder a wire to get the 12v + in place of having a blue wire.  I know I can use one of the track wires to get half wave, but I don’t want to.

Can anyone help me out?

Thanks.

Craig.

Yeah, you were the one who asked this exact question last year.  :D
Here you go: https://www.therailwire.net/forum/index.php?topic=45688

I also do not like to use the track wires. The above thread also shows how to obtain the "real" blue output from the rails using 2 diodes (bf it is not convenient to use the blue wire from a decoder, or to minimize the number of wires between a tender and the loco (if the decoder is in the tender).

Thanks Peteski. I knew it was here. I searched and couldn’t find it.

Would the blue wire serve as the common for say, the rear tender backup light?

Blue wire on DCC decoders is a common positive voltage for all the standard function outputs, so yes.  Or if you mean the alternate dual-diode circuit, then also yes.
