I have a older 2-8-0 Consolidation I bought from someone on the forum that has a BCR so the battery is not installed. It is the PS2 3V electronics board. I added a LED headlight and a back up light with an upgraded speaker with an enclosure. The locomotive seemed to work fine on my roller test stand and then on my test layout.
Recently when I go to speed step 1 on the DCS controller the speed seems to take off and on the test layout is very jerky. I cleaned all of the wheels, rollers, etc. and there was a lot of dirt build up. However the performance did not change. I did a feature and a factory reset without any performance change as well.
My suspicion is the motor flywheel electronics stopped working so the motor controller continues to apply voltage. Does this seem like a reasonable root cause? I am going to confirm later today with a DMM/scope.
What other visual or measurements can I take to confirm the issue? Are these boards available or repairable?
Thanks, Bill
