I have a Lionel JLC H7 (6-38058). I've never been satisfied with its low speed performance so about a year ago I bought a Cruise M steam kit to see if it could improve the engine's low end. Yesterday I finally got around to installing it but it doesn't seem to be receiving the serial input. The engine takes off as it were in conventional mode and I don't see what I may have done wrong.
I have Pin 1 on the J1 10 pin connector connected directly to pin 24 on the R2LC (blue wire in the picture below)
I checked continuity of this connection from the soldered side of Pin 24 to the soldered side of Pin 1 on the CCM and it checks OK. Note that I cut the black wire on Pin 10 of J1 as the instructions call for. Also, the Lionel 10 pin connector did not come with a wire on Pin 2. ERR sent a green wire to install on Pin 2 and run to a wire bundle connected to the tether. In the second picture note the blue wire coming from a connector on the mother board. This is also a serial line from the R2LC.
In the picture below this is the wire bundle that the green wire was to be added to. The purple w/violet stripe wire goes to the IR tether. So this connection has both the serial line from the R2LC and the Serial Out from the CCM connected to the same point which I don't understand how that would work.
When I try to run the engine, the sound system comes up. I can blow the whistle, ring the bell, change the volume, etc with the Cab2 remote. When I turn the throttle the engine does not respond, but several seconds later it takes off a full speed. Once it takes off I can stop it by pressing the direction button. I suppose the sound system works because of its separate connection to the serial line, but why am I not getting the serial signal to the CCM?
I went so far as taking the 10 pin connector that ERR provides in the kit and only hooked up Pin 1 to the serial line leaving all the other pins unconnected and disconnecting the serial line going to the IR tether. The engine takes off immediately and of course the sound system does not start up.
Any advice is appreciated. I don't see what I may have done wrong and I hope I didn't mess up the CCM.
