Hi All,

 

First some background.  I am fixing an older TMCC engine for a club member.  The engine is a CNW 10 wheeler (6-38042) with a wired tether.  When I got the engine, it only ran conventionally even if the TMCC base was connected.  I assumed the R2LC was bad, and confirmed this by replacing the board from one of my engines, and it started working fine.  So I ordered a new one from Lionel (69R2LC08) and installed it tonight.

 

I programmed the board using the following sequence:

 

Eng 61 Set (whistle confirmation heard)

Eng 61 Aux1 4 (whistle confirmation heard)

 

I then turned off the power and moved the program switch to run.  I reapplied power and addressed the engine and nothing happened.  The headlight was off and the marker lights flashed.  I also tried it in conventional and it only ran with the program switch in the program mode and it only ran forward (headlight and marker lights were fine).  It did not run in Run mode.

 

I tried this both on my test track and on a mainline closer to the base.

 

Does anyone have any ideas on how to fix this or what I did wrong?  I am wondering if I got a bad board.

 

Thanks in advance.

Take your continuity  meter with one probe on the handrail antenna and the other on ground.  If you get continuity you did just what the guys stated on disturbing the antenna and it is not working.  With the cab off the locomotive and the antenna wire connected, take your meter and put one probe on pin 23 on the R2LC and the other on the antenna and let us know what you have.  When doing this, connect a jumper wire between the cab and loco frame.

hi all, I finally had a chance to look at the engine.  Everything looked OK when I did the continuity check; the antennas did not touch ground, and pin 23 had continuity with the antennas.  I tried reprogramming the engine again, and turned it to run after 2 minutes. I had the same results as before, the engine did not respond at all when in the run setting, even though it responded fine in programming mode giving me the appropriate whistle responses.

 

I assume at this point I have a bad R2LC board.  Can anyone think of anything else that might be wrong?
