K-Line Geep won't move

Make sure run/program switch is in run position, might be in program and that would lock out the reverse unit.

How about some still shots with better resolution?  The picture is fuzzy and jumping too much to really see anything.

Thanks guys - The switch was set to run and since I do not have a TMCC controller to reprogram anything at this point, I saw no need to tinker with that aspect. I will take some close ups of everything and post.

Here are some stills from front to back. Can't get pics of underside of the board without disconnecting everything.

Does it get hot? Smell of anything burned?

Can see a clipped red wire in the pictures, is there a corresponding clipped black(?) wire like on the connector? What is going on under the black tape?

One issue with some K-Line stuff is they route track power through the motherboard, and a trace on the motherboard gets cooked.  Do you actually get track power on the DCDR red and black leads that go to the lower black plug?  The DCDR is the vertical board in your last two pictures.

Looks like a candidate for an ERR up grade...

BOB: No burning smells or anything abnormal there. I pulled the electrical tape and it's just covering the solder joint of the resistors to the LED's. I will re-tape it a little tighter for protection.  I fished around under the two caps and was able to pull out a black clipped wire next to the red wire that was shown in the previous pics. Two clipped wires - especially black/red - probably isn't by design... but where should they go? Could they have been connected to the loose black 2-way molex pictured at the beginning of the video?

GRJ: I pulled the black molex on the DCDR and there does not appear to be power going to the pins. With multi-meter showing 9v at transformer posts and 9v on the track, with sounds functional on loco, I couldn't draw a voltage reading of any sort on the molex connector delivering power to the DCDR.

Is the lack of power to the DCDR related to the clipped wires?

It's either the clipped wires or the motherboard as I mentioned previously.  Trace the two wires from the DCDR back and see what they connect to.  It seems you're not getting power to the DCDR, that would certainly explain the lack of motor control.   Given that there are clipped wires and the like, without actually tracing things out, it's hard to say what you have.

You may have already, but you might want to try the switch in both positions. I only have 4 tmcc engines and two out of the four have that switch mounted backwards from the factory. Ie , make sure you aren't just locked in neutral.
