TMCC Conversion works only with Boost Button with DCS Remote

Badge109OGR Forum Member SUPPORTING MEMBER

I recently purchased a Williams GP9 that had been converted to TMCC by an unknown person. I have a Legacy base hooked up to my DCS and solely use the DCS remote. The engine added into the remote with no issue. The sound works, the electrocouplers work front and rear, the horn and whistle work. The lights change direction when I press the Direction button. When I turn up the speed the engine sounds speed up, but it doesn't move.

BUT - the only way to get it to move is using the Boost button. I have a number of factory installed TMCC engines and don't have this issue with any of them. This is the only engine I own that is a conversion.

Anyone have any thoughts as to why this would be?

Thanks,

Matt

DO a reset of the R2lC. Code 8 for diesel should work. Do this just with Legacy/TMCC control. If that does not resolve it swap in another R2lC. Type of upgrade could matter. Some folks upgrade with modular lionel stuff, others use ERR. I have seen this in lionel engines and a R2lC swap fixed it. If not that might be a motor driver board issue, but again it matters what was used to do the upgrade. G

Having some pictures of the boards used for the upgrade would be a big help.

As you can see from the photos, it appears to be an ERR board. The plug that is connected to nothing... What should or could it be connected to? Let me know if you guys need any other photos.

Thank you!!

I just noticed the bottom board says "Cruise Commander V3.4"

That's a very old Cruise Commander. I'd start by swapping out the R2LC, that's the board perched on the Cruise Commander main board. The plug that is loose is hanging next to the audio board, I'd have to know what the other end is connected to for any kind of guess as to it's function.
