Thanks for sharing. For fear of damaging things, I would not have the nerve to try that. Well done!
is it possible to switch an older DCS locomotive from the thick tether wire to the tetherless connector?
George, it's not really practical to switch to the "wireless" drawbar, there are hardware mounts on both ends that have to be there to support it.

About the 1.8 amp PTC, is this a standard size for all small loco's that you install? I would guess that for a larger loco ( which probably doesn't need the extra set of roller(s) since it usually has 2 to 4 rollers under the engine), it would require a larger PTC amperage rating. Maybe you have never experienced this with a larger loco. If you have, what would be the size of the PTC value in this case. Could you supply the part number of one or both PTC's and the latter PTC's amperage rating. My guess is you got the PTC from Digikey. Thanks for sharing the experiance, it's great info!!!
I use from 1.3A to 1.8A for these. I happened to be out of the 1.3A ones or I'd have used one here. Truthfully, I doubt you'd ever need more than a 1.8A trip for any locomotive, remember these are only for momentary power loss, and it takes a lot more than the trip value to instantly trip a PTC. I get the PTC parts from Digikey, you are correct. Since it's a #22 wire to the tether, I figured I could "risk" a 1.8A trip part.
