I have an MTH PS-1 Genesis that the rear coupler gave out. The metal surrounding the coil looks like it has the zinc pest casting impurity like my Amfleet couplers had before replacing them. Has anyone had this problem with proto-couplers? How much is a replacement PS-1 rear coupler for a Genesis and is it easy to replace? Any suggestions would be appreciated.

Replacing the proto-coupler isn't really hard. You'll have to drop the truck from the motor to remove the pilot. Then you can get to the "T-Bar" that centers the coupler when you remove the "E-clip" from the bottom that holds the coupler in place. All you need to do is cut the wires and re-connect the wires from the replacement.
E-mail me off-list. I may have one lying around in my parts box.
If Matt doesn't have one I have them in stock or a LHS near you may. You will need to solder wires. G

If anyone knows the MTH part number for a 20-2189-1 Amtrak Genesis rear proto-coupler please let me know.
Thank you
It's a standard 2" coupler, I have tons of them in my parts box from conversions. PS/1 locomotive couplers have the same impedance as Lionel couplers, so either will work.
MTH has most PS-1 locomotive parts list on their site. Here is your locomotive's. It's item 104, #DD-4000001, which is the same as the front. If I remember correctly, the PS-1 Proto-Couplers came in two sizes, long and short. Looks like yours is a short, and MTH still has them for sale.
