It was in with some other newer digital locos, (I only run steam and diesel locos as I don't use overhead wires). I had to enter this loco manually into my CS3 due to its age. Upon calling it up, the lights flicker, and when it runs it does so in a jerky manner. I opened it up, but see nothing obviously amiss. I am suspecting a faulty wire or connection with the pickup shoe, as the lights flicker when it is standing still. Has anyone encountered this problem, or have any insight into the issue? Any help would be appreciated as I don't feel comfortable selling it when it isn't working properly. Regards, Dave

The combination of 6090 decoder, light bulbs, and CS3 flickers a lot due to poor programming of the CS3 TFP. This is by design. Can be fixed by changing the connection of the light bulbs in the loco. Or by getting a 6021 or an ECoS controller. Jerky running must have a different cause. Maybe dirty wheels, dirty axle bearing or poor contact somewhere else. If the jerky running is accompanied by loud noise, then maybe the rotor bearings just need lubrication.

I would start with a check of wheels for dirt build up. After that a drop of oil on the motor armature and gears then try running it for 10-15 minutes continuously

I purchased a used 37803 V200 with similar issues some time back and sent it to Scott at Helmuts Hobbies. In addition to a thorough cleaning, new armature, traction tires, lamps and brushes, he installed a LokSound decoder. It runs even better now — perhaps better than it did when new — and the sounds are awesome!
