RP lighting question - fried circuit?

[BP125V]

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

Its possible that you fried just the LED's because of the absence of the resistors. As a trouble-shooting step, I would suggest replacing the LED's (or at least one of them) first and see if that fixes the problem.
