Hello,

I have been using RP for several years now and doing my own hardwire installs and LED upgrades without any issues.  However, for some strange reason, I just completed an install on a HO Bowser SD40-2 and forgot to install a few of the resistors on some of the new LEDs.  Headlights worked and then when I turned on the ditch lights they, and the headlight blinked and now none of the lights work. However, loco runs fine and sound still works.

Does anyone know how the lighting circuit works in the LM-3S?  By that I mean is it one circuit that I potentially fried and now none of the lights will work?  I had wired with the 9 pin yellow, white, green, and 6 pin green and purple.

Thank you,
Bill

Are you sure that it is DCC Ready and not DCC installed?

Looking at the instructions I could find on the web for this loco and a few videos, and I will admit that I could be wrong on this, it looks like this is a DCC installed loco and the 21 pin slot is just for Bachmann's sound module and not for a separate decoder. The circuit board itself appears to be the decoder from what I can see.

Looks like a hard wire, or at least a different mother board may be needed. This PDF from Bachmann might be of use in this process.

Reason: moved to more appropriate board.

there are 3 AA batteries in my HC-2b.

while I usually believe all brands of AA batteries (of the same type) are created equal, I have had better success in other application with the Energizer brand rechargeables (but not Li, as noted by others).

Thanks for that comment LVRR1856.
Yes - all of my HC's are individually named. They weren't however discovered/known to all of the others. I've since effected that change.
I will repeat my experiment of linking locos and cycling track power, etc., to see if this makes any difference to as to when any particular HC can recognize the linked locos.
