Analog N gauge layout shorts
Posted by Dave K on Thursday, January 20, 2022 12:08 PM

I have one power pack and three DPDT switches.  one DPDT for the main line and the other tow for reverse loops.  The simple reverse loop is fine but the main and the other reverse loop show a short.  Any suggestions to fix?

Hi. You might want to post the plan, the location of the blocks and wiring details.

I checked all of the plastic insulated joiner sections and behold:  The reverse loop that is working is properly insulated.  However, many other joints insulated with the Atlas insulated joiners are not insulating thus causing the shorts.  I will try to fix this with the insulated rail joiners, checking for insulation as I go.

What is confusing me is that I used a DVM to check continuity in the rail before the insulated joiner and the resistance is the same.  Pictures of the rails below.  The one reverse loop that is working has both sets of insulated joiners working.
