Loco Stopped. “Motor Over Peak Current”
MtRR75:
Still More Info:
(1) The Motor Max Current is set to 220 mA, which is the same that it was before this trouble started.
(2) I tried turning the speed knob VERY slowly, to see if the current on the Info screen gave any indication before the “Motor Overload” error message froze the screen. Out of about half a dozen tries, I got ONE piece of data. One time, the Motor Current indicator flashed for less than a second before the “Motor Overload” message took over. I am 90% sure that I saw the number “60” or “69”. And I also saw the vertical bar current indicator flash for less than a second. As best I could tell, it was between 60% and 80%. Remember that the speed knob was turned a tiny amount.
(3) As for swapping out LMs, I can’t do that. Remember that the LMs were installed by Yankee Dabbler. They are hard-wired – no plug. And I don’t have the skills to solder such small wires.
(4) What I can do is erase the Heavy Steam ULT file on this LM and recopy it from the HC-2. The rest of the files on this LM are all performing fine. And the copy of the Heavy Steam ULT file on the HC-1 has been successfully copied to, and run on, four other locomotives. So, I see no need to recopy the file from the internet to the HC-2. I will let you know what happens.

Yes, but the motor may be drawing more than that if it's developed a fault.

Going straight to overload does kinda indicate that there is a path of low resistance from one motor output to the other motor output external to the motor, or there is a fault with the motor that is causing it to draw much more current than before, triggering the LM's overload because it's expecting no more than 220mA.

Are you saying that YD removed the 9 (and 6) pin sockets from the LM and soldered directly to the LM's board? If so I'd be looking here for anything awry too.

I'd be very surprised if the sound file had anything to do with it but anything is worth trying.

SWA737:
I just had a similar problem on a recent Railpro conversion. This is my 43rd converted engine. This is the first time I messed up setting up the controller. I set it on the track and begin to run it prior to doing the “Motor full load current. Just completely forgot to do it first. It ran for just a couple of seconds and then that was it. I then tried to go back and do the test but when I did, it said test failed and the little caution yellow triangle pops up saying “ Motor over peak current”. Did I possibly burn the motor up? The lights and sound work well.

SWA737,
I wouldn't think you've killed the motor, or damaged the LM either. I've run LM's before in my LM tester without setting the Motor Full Load Current without issue that I can remember, though it was all non loaded stuff (ie just a bare motor) just to check the motor outputs worked.
A couple of things you could try are:
* Removing the LM from the HC and then redetecting it. It should indicate that the Motor Full Load Current test hasn't been done and the test may work this time.
* Manually setting the Motor Full Load Current to a higher value and then trying the automatic test again.
If neither of those work it might be time to find out what the motor actually draws.

Can the LM be used in a loco without setting Max Current at all?
