Lights work in conventional mode only. SOLVED

I don’t think this is a legacy engine. If it’s TMCC engine then it needs to be identified as such in the cab2.

Did you try pressing AUX2 when it was running under command mode?

Does this engine have LED lighting?

Hi John, I’ll try aux 2 but Just to confirm, when the cab 2 remote is set up for TMCC RS it doesn’t display numbers, correct? So the #1 key is actually the increase volume icon, etc, etc?

Oddly enough the engine has incandescent and LED lighting. The engine originally didn’t have front daytime running lights. I was surprised they had installed LED alternating running lights free of charge when I returned it for repairs shortly after purchase. They may just have sent me a new revised engine. As a result the headlights and markers aren’t as bright.

Hi Rod, thanks for responding but yes, it is set up as TMCC RS in the cab 2.

The reason I ask about LED's is in conventional mode the headlights are fed with full wave track power.  In command mode, they're fed with half-wave track power.  So, if they're wired with the wrong polarity, they'll still light in conventional mode but not command mode.  This was a well known issue when replacing the R2LC-C07 with the R2LC-C08 for some Atlas TMCC engines because the polarity of the lighting outputs in command mode changed from positive to negative in reference to frame ground.  Apparently, Atlas never anticipated that the R2LC would go bad and the replacement would be a later version.

Add another case of beer to what I owe you John! I think it was Aux 2-2  that fixed it.

Thanks…Rich

AUX2 toggles the lights on/off, and the R2LC remembers the setting.  It doesn't affect conventional running, so it's a fairly common mistake.   Nice that it was a free fix.

Alright, nice ending. Thanks for sharing.
