Help with Lionmaster Class A 6-38049

Not moving would actually be far more likely to be the wiring or the DCDS, I really doubt it's the motherboard.  It could be the R2LC, but that's less likely than the DCDS or wiring.

The DCDS for your locomotive is not available, but they have a reference to a replacement.

This is the suggested replacement for the DCDS.

Thanks for the recommendation.  Your response made me remember that several years ago I upgraded a tmcc gp30 to cruise M.  Looked at the old board I have in my parts bin and its markings match exactly with the HM5 replacement part.  I think I might try that before I order.

If it's a functional board, that should resolve if it's the DCDS.  If that exhibits the same symptoms, swap out the R2LC and/or start looking at the wiring between the motherboard and the DCDS.

Thank you for the guidance on how to go about fixing this issue.  I will follow your recommendations and report back what I find. I did pick up a R2LC in the sale just in case. Have several tmcc engines anyway.  Also picked up a pair of siderods for the LC+2 dockside switcher that waddles down the track.

If you have other engines, you can swap the suspect R2LC into a working engine and see if that's the issue.

It will respond to the startup and shutdown commands, crewtalk, directional lighting and will even give one initial choof sound when given the forward command, but will not budge.

With the parts sale this weekend, I would like to take advantage of the discount, if I need replacement parts.  I currently have the I.R transmitter, R2LC motherboard, and R2LC radio receiver in my shopping cart.

I am not confident I am heading in the right direction or completely missing the probable cause of my problem.  Any help would be appreciated.

I recently experienced odd behavior and very similar symptoms with my Lionmaster A. Turned out that weak batteries in the CAB1 were the cause so check those too.

Still not a bad idea to stock up on various electronics while they are available, especially if you really like the engine.
