As an alternate, if you can hook up an ammeter and test the current draw, just retard the loco so it can't move yet still allow the drive wheels to slip and spin. If the current draw at wheels spinning doesn't exceed .5 amp (1/2 amp), a 3/4 amp 123Z decoder should work ok.
Bob is tht a standard for current draw and if it does exceed that do I just add 1/4 amp to the amount of current draw? I do have and use an ammeter?
Geez I feel like I stold this thread from the OP.
