Hi, just about to connect this to the bus. Does it matter which way round the wires go, provided I connect one to each. Side of Bus. I forgot to write down which way I had it before. Thanks.

Surely it connects to a decoder not directly to the DCC bus.

Turntable motor from memory, goes to the bus. My worry , was if by reversing the wires, it caused decoder to blow.

If you are talking about just powering the tracks on the turntable then a lot depends on what you are going to use the turntable for. For a simple 180 deg turn the polarity in the TT tracks needs to swap that can be done with a split ring and a couple of wipers on the spindle alternatively use a reverse loop module.

If feeding a number of tracks off the turntable as long as all the tracks off it follow the same wiring protocol for left and right rails AND the turntable only turns one way and returns back the opposite way and you have not done a 180 deg turn, than there is no need to change polarity.

Thank you. My TT, is a Frateschi, super item, and works on a mouse click, within Hornby Railmaster, schematic. It can take 18 tracks, although in my new scheme, only using 3. Trouble with taking things down, is you tend not to label the only thing that actually, may have needed one. Labelled all the point motor wires etc.
