Thanks Jon.......So I am correct that this loco should run with only 1 rail grounded ?. Again, If I open I void the warranty. How many leads are on that switch? How would I know where to check for continuity?

Yes, should work with one side grounded, but that’s not optimal.

The tender has 6 screws securing the shell. You won’t void the warranty removing the shell. Just be careful to not pinch the chains or wires when reassembling.

The switch has 4 leads and a crossover wire on the 6 terminals. Check continuity between the center terminals and each end terminal with the switch in the tested direction. If bad, suggest following Gunrunner’s diagram to bypass it or use the ASC locator to find an authorized service center.
