Reply to ""Surging" issue on a PS2 engine"

Stan,

Thanks for your reply. I have to check again, but I think the 3 wires running from the tach reader are as isolated from the motor housing and its leads as you can get. Even if they weren't, I don't see how the "noise" from the motor leads has any bearing on the surging issue. If running at normal fixed operating voltages and that scenario you presented were true, then my inclination is that the result would be excessive surging regardless of the set speed of the locomotive, would it not?
