stan2004 posted:Early on PBJ said the slowdowns occur even with at 10 sMPH. Even if there were huge voltage drops from wiring or whatever, it's hard to believe this drop would be more than a few Volts. Any PS engine (with no rolling stock load) will run 10 sMPH in command mode with only 12V on the track. So for it to slow down in command mode (i.e., when commanded to 10 sMPH), the voltage the PS boards receive (after going thru the wheels and rollers) would have to drop below 10V or so.
Hence, I'm curious what happens with the problem engines when run in conventional with speed control TURNED OFF.
I guess I should mention too that the slow down/speed up issue often occurs all in the same electrically isolated block. Meaning, the issue starts in one block and resolves itself in that same block. The locomotive doesn't need to leave that block and enter the next one for the issue to resolve itself. Not saying it always occurs in one block, but it often does.
C. Jones - no, I haven't done this and will (thanks), but I will say that I had this issue from before we even owned Legacy. What I can't recall is if we had it before we had TMCC. Will def check.
Thanks
