It's not always the technology that gets you! I've been fitting a LL SW1200 switcher with DCC. During the installation I got to a point where I could test the system with the chassis on the rollers and the shell (with the electronics) next to it, upside down. I set the long address to the engine number, and after some fiddling with resistor values for the lights it all worked fine. When I finished the installation I married the chassis and shell, and put it on the track for a test run. Darn thing wouldn't respond to any commands. I knew it was live because the engine was idling (it's a sound decoder), but it wouldn't move, light up, hoot or anything. I got the books for the decoder and command station out and checked everything in the troubleshooting guides - no good. So then I put it back on the programming track to read out what the settings were (expecting to find it had somehow lost them). But it hadn't - all present and correct. Except! The address of the loco was set to 292, and I had been trying to command loco 262. I looked again at the engine and 262 is indeed its number. But of course the shell was upside down when I first programmed it.
That's funny. The sad thing is that is the kind of things that happen to me when the shell is right side up.
Mike- Welcome to my work bench. Ha ha. When it comes to goofs, even though not DCC, I've been there. Done that. *Sigh* Well, at least no harm was done. Boxcab E50
Reminds me of when I repainted N&W 578 at the museum. somehow one side of the cab ended up 576. Took about an hour till I noticed it oops. Mike
