Legacy SD70ACe cab blinks once, continuously, but runs fine -?!-

Read your manual on how to do a factory reset .. This will fix this ..

Thank you – it worked!

 

However, it was not that easy to find how to do the locomotive reset.

 

• The 72-8261-250 5/09 manual I have for that SD70ACe locomotive has a reset listed on page 23, but it is for TMCC; not for Legacy.

 

• A newer 73-8966-250 8/13 manual I have for the EZ44AC locomotive, has the locomotive reset procedure the same as for assigning the ID number, and this did not work to stop the blinking cab light.

 

• The Legacy manual I have does not have anything on resetting the locomotives.

 

• And as I said before, the reset [R] key did not have any effect.

 

Finally, after a Google search that brought up manual 82-8314-250 07/10 for Vision Genset, I found a reset sequence that worked!

 

Here it is: (in case anyone else can use this information)

 

===========================================================

REPROGRAMMING YOUR LOCOMOTIVE TO RESTORE FEATURES

1. Slide the program run switch to the PROG position.

2. Plug in and connect your LEGACY Base.

3. Place your locomotive and tender on the track, then power up the track.

4. Press ENG and enter the locomotive’s ID#.

5. Press SET.

6. Press INFO.

7. Press AUX PROG.

8. Enter 2 for this particular locomotive. (But it worked for my SD70ACe!)

9. Press CTC to exit programming mode.

10. Turn off track power and wait ten seconds.

11. Slide the program run switch back to the RUN position.

 

At this point, your locomotive has been reset. Restore power to the track and operate the locomotive as usual. Be sure to use the ID# entered in Step 4.

Certain locomotives, and certain cars,( the stationsounds passengers cars if I remember correctly) have a "strobe feature" (no idea why) that can be inadvertently activated.

 

 This has come up on the forum in the past, on a few rare occasions.

 

Maybe you somehow activated this "strobe feature" on you loco accidentally when programming the recorded session.

 

Just a guess, only Jon Z would know for sure.

Alex also keep in mind that the blinking codes do not apply to your locomotive. The Conrail 1209  has earlier version legacy electronics on board. A simple reset should solve your problem..

The simple reset, as I mentioned in my first and last posts, both with the reset [R] button on the Cab-2, and via the simple ID assignment, which is supposed to do a reset, Did Not Work.

 

I took the longer reset sequence to make the cab light stop blinking. I understand that it might have not been a code, as there were none listed in that specific engine's manual.

 

Thx!

Did you accidentally hit the set button?  It may be in its stall/ minimum start setting.

I really don't know, but it is running fine (as has been the case all along) except no more blinking!

 

Alex

I think J hit the nail on the head.....

The set button for stall blinks the headlight, not the cab light. 

 

I was thinking maybe the cab light was driven by the R4LC smoke output.  I don't know this to be a fact, it's just that output is unused in this locomotive for it's original purpose.  That locomotive uses the AC regulator for smoke, so the smoke triac is not used for smoke.  In the TMCC world, many times people get them configured for a beacon and wonder why the smoke unit pulses on and off.

 

I have had a couple of older legacy not the new ones with blinking cab lights and a factory reset has always fixed them. Even though it acts like the new ones ..regardless it's fxed now

This fix worked on the same issue I had with my SD70ACe Pennsy/NS diesel.  THANKS!!!!
