DCC system shorts out


 

Good day everyone, I have a question. I have an N-scale layout. I am using Peco code 80 flex track with Peco Insu-frog switches. I started running feeder wires the other day and I found that is If install more than one feeder my MRC system shorts out. Sometimes it occurs when I through a switch and sometimes the system shorts out the system with more than one feeder. Any ideas out there?

thank you,

Sounds like you¡¯re crossing bus lines and creating the short through the wiring itself.

Make a test buzzer, ?how to on wiringfordcc.com. ?Use the buzzer when doing your wiring. ?It will buzz if you create a short while wiring¡­?

, plz pardon the spelling!

Take a look at your switches. They direct power in different ways. You may need to add insulated joiners on the diverging end.

When wiring, I often do one rail at a time. I'll drop all the back rail feeders to the bus then do all the front rail feeders.
