I put a Cruise Commander DS in a Lionel Copper Range 060 with no difficulty, followed the procedure in the manual to the letter. But the engine seems to run in one direction...or the other. That is, it will run forward, hit reverse and it still runs forward. Then at some point there it will go in reverse and regardless of the TMCC commands entered on the CAB2, still runs in reverse. I tried the push down on the button, rolled the button forward to determine direction and this worked slightly once in awhile.
I looked at pin 16 on the R2LC with a scope and it sits at about +6 vdc when always running in reverse after button pushes with a little millivolt change when pressing the reversing button on the cab. I haven't been able to catch it when it actually does reverse or forward...ie, when I have a successful change in actual motion. What are the proper voltage changes on pin 16 of the R2LC? I take it that there must be a voltage level there applied to the motor board that reverses the direction of the H motor driver transistors. Is there no schematic of these boards available? At first I thought that the motor board was at issue, but since there is no real change of pin 16 on the R2LC when reversing, I am thinking the R2LC is at fault...not that it is a hardware failure, but maybe a signal issue. I tried another R2LC board and had the same results.
I did notice that when running with the boiler on which includes the lights, the reverse button cycles the rear light on and off reliably...but the engine still continues going the same direction. Also when running, I get a flickering of the headlight and cab light. But when sitting still, throttle down, the lights are on steady...ie, there is a good TMCC signal getting to the engine. I put a 1uF bypass cap on the motor but it has had no effect on the problem.
BTW the horn works and sounds when programming the ID, the Features, etc.
I put plain TMCC in a Docksider, it was a challenge, a reverse board sized unit would have been super!
