Gunnerjohn, my railroad would still be defunct without the help you have given me to rid my locomotives of the dreaded Nicad batteries. I am happy to report that 28 of the locomotives on my roster now have "Roll Your Own BCRs", and I have only a few left to do. I did make one mistake however. I connected the (+) of a capacitor pack to the boards in my GG1, and unfortunately I put power to it.
Since I corrected the polarity error, the GG1 has lights and sound, but no motion.
