My C-19 started drawing a huge power load and basically won't run without 100% of either the MRC 6200 or the PH Hobbies transformers.  Both of these transformers run a variety of large locos at low power level.  When I apply power to the track the C-19 Phoenix sound system works perfectly, but little power goes to the loco. I have cleaned the track.  Any ideas why it's requiring so much power? It has been running flawlessly for several years.

I now have the Zimo mx 697 decoder installed in my C-19, running on an analog, DC track.  The sound is good, but limited on DC.  It does not include any bells and whistles and no appropriate toots for forward and reverse.  I had to install a potentiometer to control the sound volume.  I tested my decoder on a DCC system and the sound is flat awesome.  I wouldn't recommend it for DC.  For DCC the installation couldn't be easier. Plug and play.  If you order from the nice people at Trainli, make sure they know exactly what loco it will be installed in.  Reconfirm your order before it is shipped. 

Hi, Loco Bill.  Well, it turns out that there was a polarity switch in the new chassis, which connected to my loco a couple of years ago.  The switch was at the end of a long bit of wiring, and I assumed incorrectly that it was a replacement smoke on/off switch.  Since I don't use smoke in the Big Hauler, I just left the old switch installed behind the boiler door and tucked away the other switch in the new chassis. Upon removing the old body today, I saw the switch. I put the chassis on the track, moved the switch, and ta-da! polarity as I wanted it.  Thanks much for your input!

I spoke with the gentleman (I think the owner or manager) at Train Li, which handles Zimo, and he told me the Zimo Mx 697 DCC would plug directly into the C-19 and provide limited, appropriate C-19 sound for my analog RR. A separate part for sound volume is available.  The MX 697 is not shown on the TrainLi website, but he said it will be in a couple of days.  The Bachmann Yardmaster suggested Soundtraxx ECO 400 but that has been replaced by the TSU 4400.  I have to research that more. Any additional thoughts are appreciated.  Thanks, everybody, for your input. Bachmann really deserves big thumbs up for hosting this forum, and for jumping in with comments.

Thank you, Yardmaster!

Very helpful. Good advice. Thanks much!

Thanks for the reply, Kevin.  MY original message/question wasn't well-stated.  I'm looking for a decoder for my c-19 that will run on analog/DC, track power, only.  I don't use DCC.  Knowing that, can you recommend a decoder that I can reasonably easily install in my c-19 2110 socket? Thank you for your help. Jim

Hello, group! I have a new C_19 Bumble Bee, and I would like to know if anyone can recommend a decoder that will plug in to its factory 2110 socket. Have you installed that decoder, and can you share any info about the install? Thank you!

Which switch?  Isn't the switch that's behind the door in front of the smokestack for turning the smoke unit off and on? There are black and red wires going to the front wheels. Are those the ones that could be reversed? I'm not very savvy about this stuff!!!

Thanks! I'll let you know how this goes.

I replaced my original Big Hauler chassis with a new chassis and then reinstalled the body. Runs great, except the polarity is reversed.  It runs the opposite direction of all my other locos. How do I reverse the polarity?
