[ BR 601 posts ] I hate soldering an ESU PowerPack to the Loksound 4 decoder. Given the circumstances, this is pretty well done with reasonably sized solder pads, but I really don't like soldering on a $100+ decoder board. Once that was done and visually inspected, I connected speaker and a motor to the decoder and fired up the Mobile Station to double-check proper operation. Let capacitor charge for a couple minutes, fire up the speaker, disconnect the lead, aaaaaand ... urgh. Nothing. Yes, the motor is the one I replaced from Roco 43012 I verified the programming of CV 113, which controls how long the decoder pulls power from the capacitor. It was zero. Well, yeah, that's not going to work. Re-program to 150. Let charge. Try again, aaaaaand ... nothing. Urgh! No matter what I programmed into CV 113, it was zero when I read the value back out. Alright. Something is preventing the decoder from accepting the PowerPack. I double-checked my solder connections. All good. Scratche...
