ERR CC-M and older TMCC?

George, the feature code for steam is AUX1 4 though it shouldn't make a difference here. It acts like Cruise is turned off. Check the ERR manual for the keystrokes to make sure Cruise is on. It should start within 2 speed steps, preferably the first speed step.

If still no joy I would turn the flywheel by hand to verify no binding.

George, first thing to check is indeed if cruise is enabled.

The engine should start moving on the first speed step if cruise is enabled.

Thanks PETE & JOHN.  I did do the cruise on sequence with the Cab2.   I will redo the sequence this afternoon and let you know.  Thank you.

FWIW, AUX1/8 is the code for diesel with smoke, the code for steam with smoke is AUX1/4.

BTW Laz, the keystrokes for Cruise ON is done in RUN mode as is big/small motor, 32/100 speed steps, and nudge. Only engine ID and feature code are done in Program mode.

Hi GUYZ,

  I did the reprogramming in the run mode for cruise, small motor, and 100 steps, still no change.  I will now open it up again and check the motor to see if there is binding.  I’ll report back, thanks again.

George, the parts list for this engine shows a strange wiring setup for the motor. Check that the two wires at the motor go to the 4 pin black connector that plugs into Cruise M. The photo appears to show the motor wired to 2 two pin molex connectors that usually connect to AC track power, pickup and outside rail. Obviously they can’t go to track power or the motor would burn up.

Hi GUYZ,

  PETE, thanks for the info, but my camelback has the four wires for the four prong molex. I took everything out and unhooked the CC-M.  Unscrewed the motor and took out all the old grease put new grease in and replaced the board.  Again same result.  I then took out the CC-M and replaced it with the original TMCC board.  Fired it up and acts just like the CC-M board.  I think I fried the CC-M board.  Burnt mark on the processor.  I had JOHN test one and it had the same mark on it.  I don’t know if the heat sink came in contact with the screws on the motor mounts or not. Or maybe since it is such a tight fit getting the shell back on that something grounded out?  Oh well just going to keep it in TMCC a mode for now.  Thank you GUYZ for helping me trying to get this figured out.  I might try again when I get another board.

Here is what the burnt mark looks like as what JOHN had sent me.

There must be something wrong with the wiring, the one I got from you to test has a nice scorch mark on top of the processor, and needless to say, doesn't function well!  Does the replacement have the same mark?

I don't know how you do this if all you did is wire serial data to it.  Are you SURE that the serial data really comes from pin-24 of the R2LC?  The other two plugs should be pull them out and plug them in.

I hasten to add, I've done a few CC-M upgrades on the TMCC Camelback and it's a VERY tight fit!  You may be shorting something when you try to put it back together.  I actually ended up taking a couple connectors off the MB and sky-wiring them to make it all fit comfortably.

Yes JOHN all the wires were connected right.  Pin 24 was connected right.  I have done a few of these but nothing that fit so tightly.  I just think that something shorted out with getting the shell back on.

Yep, thinking back I had to modify the heatsink to move the board a bit as well.  It was a PITA mechanical job, usually these are dirt simple to install!

Thanks again JOHN for your help along with PETE.  Maybe I’ll send it to you to modify?  Just kidding, I don’t think you need more gray hairs.😉

I charge extra for Camelbacks, they're really a PITA to install these in.
