MTH Dreyfuss PS-3. Runs 80% Loop OK. Runs jerky on 2 areas. Areas about 1 foot long. When it hits the bad spots the amps jump up from approximately 3 amps to 6.2.
MTH Hiawatha PS-3 runs perfect for comparison. My other 20+ engines never behave poorly. Trying to rule out track power.
I probably overfilled (I tend to) the smoke (about 20 drops). With the loco smoke off I get perfect operation. On the loco motor, it sounds jerky, not smooth or steady when at bad area Since it acts bad with smoke turned on I suspect electronic. Let it dry out? Or has someone experienced this?
Star wiring, ZW-L, up-to-date remote and TIU. Signal all 10s. Insulated power drops every 3 or 4 sections (approx. 36”).
