Hi there, I am just building a new layout and I am currently doing the wiring. I am planning on two bus's ie up line and down line so if I get a short on one the other line will keep working. I have just finished connecting dropper wires to tag strips using seperate tag strips for up and down lines checking with a multimeter has I worked. I then connected a Cobalt motor to the tag and the psx circuit breakers to the two bus wires. When I put the meter across the tag strips or the rails it then shows a short, by the way the Cobalt is still in the centre position I have not set it up yet. Tonight I dissconected the Cobalt and connected one of the bus wires direct to my NCE SB5 bypassing the PSX and a train run ok no shorts. Is it just a matter of the units needing to configure with power ?.

By the way I am glad I joined this site, I just found your diagram on how to wire the Ip motors via a accessory bus. I have 17 Digital IP motors to fit on my fiddle yard and I will be using the motors in the reverse direction becuase I have feeds at the toe end. I am on on N-gauge by the way, wiring the motors will be easy I am using a Cobalt Alpha Central for them.

The Cobalt motor is break before make, so should not be an issue if in the centre position.
However, if the arm is slightly off-centre, it will make a circuit one way or the other
I note that you have posed the same question on RMweb and it seems that testing is progressing well.

It is likely that you initial measurements with the meter may have been confused by testing for shorts whilst the your PSX and/or Cobalts were connected across the DCC bus.

Thanks newbryford, yes I have been trying to find out for a few days. I initally posted on the n-gauge forum but no body replied and tonight I tried RM web. I then found this site and joined here thinking I will more likley get a explanation on here. I have been using psx circuit breakers for a few years now, I have configured them with reset switches, lowered the trigger voltage for n-gauge and on two I have added led warning lights. I was geting worried I was doing my wiring wrong, I have alot to do yet all my fiddle yard with 12 tracks etc and lots of feeds. I am just wondering if the meter was confused has you say I will find out when I connect up. Thanks for the reply.
