Rear Head Lights wont turn off in forward Lionel Legacy GP7

I moved this to the correct forum since this is not a 3-rail scale topic per the definition in that forum.

Being an R4LC based control system, I would follow the manual to reset the engine to defaults.

I tried finding a PDF version of this series (6-28xxx) but could not. Hopefully you have the original manual. I just do not know what the specific reset code is for this engine.

AUX1/2 for early Legacy diesels, that's a pretty universal value.  AUX/1 for early Legacy steam.

I have a Lionel Legacy 6-28598, Santa Fe. Ever since I got it, the rear head light will not go off when in forward.  And when the engine is set in reverse, the front head light wont go off. So the issue is both the front and rear head lights stay on no matter what directions.

As for the marker lights, they do change from red to green depending on what direction the engine is running.

Does anyone have any idea why the lights are not coordinated with the directions of travel?

Thanks,

RAY

Hit reset on the remote

I hate this is not an "official" link but it does appear to be the correct Legacy GP7 style manual https://www.manualslib.com/man....html?page=23#manual

Reset- AKA numeric 0 is NOT the same reset. AKA R on a CAB2- again this is NOT the same reset.

That reset, done with the engine in normal run position, just resets back to the basic starting point. It does not fundamentally change settings. Again, this is akin to dropping track power as another way of rebooting the engine.

Changing the features codes of the main controller (R2LC / R4LC ) determines major features of the outputs of that modular style control board and thus things light directional headlights and other features such as smoke unit VS strobe light or other feature are controlled by this setting. This reset is part of the changing the address function when the engine is set in program mode via switch on the engine and then sending specific TMCC/Legacy command button sequences.

Sorry you’re not correct with a cab two in the screen there is a circle with an R at the bottom. If you push that button, the whistle should sound, the light should flash and the engine returns back to its original programming for whatever the software was I have done this many times when the back up light was stuck on the tender.

Will have to check out all the suggestions. Since this is a Legacy engine, I don't think the TMCC reprogramming is applicable - or am I wrong?

Also, John, I am very familiar with the Aux1/2 to turn head lights on and off. However, when I do hit Aux2, only the marker lights on both ends of the GP7 turn off, the duel seal beam lights (front and rear) on the GP7 stay on.

I've never seen this on any of my other Legacy GP's. Got me baffled.

Just follow the manual. Why would I research the answer, find a copy of the manual for you, quote the exact section of it to you, only to have both you and "that guy" question my answer?

Further, John said the SAME THING and you blew it off too.

Also, this needs corrected too. Yet another potential misunderstanding. The little details matter.

In RUN mode- Aux2 turns ON and OFF the outputs for lights out of an R2LC/R4LC- and yes, in many models, more than just head light and tail light may be tied to this output. Again key here this is normal run mode operation.

Aux1 is mentioned because again, the FEATURE CODE setting, depending on what remote is used, may require pressing Aux1 on the remote to enable the numeric keypad (example CAB1)- to then set the numeric feature code- all while the engine specifically in the PROGRAM MODE.

If you own TMCC and/or Legacy engines- then knowing about feature codes and engine reset to what is the correct code for a given engine is an important thing to be aware of. Again, knowing it exists, knowing the symptoms of incorrect operation caused by the wrong feature code, and further, where to find that code either using a chart or using the engine manual is a huge deal.

Early Legacy with the R4LC/DCDS boards still have an AUX1-x programming code.  Modern Legacy with the RCMC, LCP2, or LCP3 do not have a programming code.

Also hitting R on the cab 2 remote will cause the lights to flicker and  then it should be back at neutral start up. I have a few early legacy engines that the back up light sometimes hangs in the on position. R always corrects the problem.

Reset is similar to dropping power, which was apparently tried a number of times.

This true, but for whatever reason I have found it cleared the issue when power on off did not.

It sounds like the wrong feature code. Try both program numbers 4 and 8. I believe #8 is the correct one for reversing headlights. Do the program in TMCC command mode, it will convert over to legacy mode.
