This is the preparation and fitting of Peco electric point motors on a model railway from start to finish. I KEEP SAYING CAPACITORS BUT THEY ARE DIODES. The gaugemaster PCU1 that I operate already has a CDU in it. The diodes stop power seepage when you throw the switch. If you are using a points control unit that does not contain a CDU you will need to buy one. The diodes stop power seepage when you throw the switch so the points get the full hit. l do have my own group on facebook if this is any good to you. "Paul Briden's model railway group".
