Hi
Problem re-occured yesterday, again with new locomotive in the consist. 2 Kato SD40, same gearing, same road number (I renumber one, don't worry) Basically, the same product. Both running à 290 MaH.
Symptoms: Jerky, one pulling more than the other. Vice versa. Slowing down, then back to speed with an acceleration surge. Once stopped and knob turned to 0,00%, one of the loco was still at 9% current, making it pull alone when direction switched, motor still humming after 0,00% got me intrigued so I checked and it was at 9%. Then, all of a sudden, one of the other loco direction was "mixed up" When on forward, it would go backward, like if I had switched the gear direction, but obviously did not, and then, it automatically went back to normal.
Very odddddddd. I felt like losing control. Which is a no no no.
ideas?
