Drop in amps

I run railpower wires to between all of my Ross Switches. Power does not automatically flow through my Ross and Curtis switches. Hope this helps. This hi-speed crossover [obviously dismantled ) has a railpower connection between the two switches.

My guess is an issue with common. I would make sure outside rails on those switches that should have ground, do.  When the engine dies you could touch one end of a wire lead to an outside rail that you know has good ground and other end to a wheel and see if it fires up. If it does you have a ground issue. If that doesn’t work Next as a test I would disconnect non derailing if you have that set up and try it. 

Thank you. I'll give both suggestions a try and let you know.

I ran power leads between the two switches and that has helped a little bit. The amps drop to .7 and sometimes the engine stalls and sometimes it doesn't. I will try fiddling with the outside rails next. Gotta think happy thoughts, eh?

What could cause a drop in amps? Here's our situation. We're running Lionel locomotives with TMCC. We're using a Z-4000 for power. For 99.9% of the layout, the draw is 17 volts at one amp. At one spot on the layout, though, where two Ross switches are back to back, the amps drop to .5 and the engine stalls. The volts stay the same. Any ideas how to fix this, please?

Thanks,

Jim

your losing the connection from the loco to the power supply

your losing the connection from the loco to the power supply or the ground has an incomplete rte back to the power supply
