Do you have the ARs connected straight to the booster or after a circuit breaker? Some CBs are so fast that they trip before the AR can reverse polarity. PSX-ARs are a great solution because they act

Well.......The track polarities are all now matching, and the locos run fine.......except...... .....for the reversing loops. I have two of them, and have circuit boards that reverse the current if

Phil T, That's amazing! I've seen bad power cords, but in my experience, they've always worked well or failed (not connected.) I've never seen one that limited the load like yours. It would have taken

Thanks for all the excellent advice. I'm now going through each block to ensure polarity is aligned. Greg Harter

I wanted to thank everyone who gave me ideas on how to fix this! I made some changes based on your recommendations and have improved the layout, even though the problem still eluded me. I went over to

Yes it matters.? while it's not DC it's sensitive to phase, so you basically treat it like DC.? If you reverse the phase from block to block it will short when an engines crosses the boundary.? At

This is correct. Using a voltmeter set to read about 20V AC, the gaps in both rails ("left" and "right") should have zero or near zero volts between the same rail across the gap (left to left, or

Yes it matters.? while it's not DC it's sensitive to phase, so you basically treat it like DC.? If you reverse the phase from block to block it will short when an engines crosses the boundary.? At

Welcome to DCC. You want to rails to match and not be reversed, otherwise everytime an engine truck crosses the gap it will create a short back to the main power supply. Use a voltmeter set to AC, to

Yes.? Thank you for the correction and clarification.

Duff or Polly, That's almost correct as far as it goes, except for the statement about auto-reversing. Only ONE of the two blocks would need one. In fact, auto-reversers that are adjacent will not

Assuming I am understanding correctly, polarity does matter with AC, but not the same way for train operation. Let's consider two of the? six blocks for simplicity, the train rinning from left to

Hi Greg. Yes, it matters. If the rails are connected backwards in one power district compared to the next it will create a short circuit when the wheels cross the gap. Even with AC, a short circuit is

I'm either lucky, or it doesn't matter....... After 20+ years, I am replacing my EB3 circuit breakers on my HO layout. I have an NCE ProCab system. I replaced them with six PSX circuit breakers. I've

I've been replace 12 gauge with 14 as I rewire to support signaling on a 4-track main, but have had no problems.? Indeed, in one section, I've even been able to get away with exceeding the maximum

AFAIK, you don't "program" the Switch Kat's address via a normal DCC programming operation. IIRC, there is a jumper on the Switch Kat, that if you short it, then send a switch command to the desired

Steve, You are probably correct. At the 10-12 level I find little difference in the workability and there is a slight decrease in voltage drop. I'll just need to see what the local electrical supply

Hmmm!? #10 wire is way overkill, harder to work with and expensive.? ?Just sayin.

I've found auto parts stores are good sources of heavy stranded wire, and the larger currents and lower voltages of automobile wiring make their wiring supplies well suited to our similar model

Hi Dale, Just checked and I think this (connecting remote indicators) will work very nicely. An excellent alternative. However, if I use the second method (run a 10AWG track buss to the right then
