If you’re using a 6V dc motor in your Lima or Hornby ringfield motor conversion, and you’re using DC control or DCC without CV5 functionality, you’ll need to consider a diode voltage dropper to protect the motor from over-voltage and current.
All you have to do is twist the legs of two diodes (arranged in opposing polarity) together and solder the joints, cover in heat shrink to insulate and then solder it inline with the wires to the motor/from the pickups or decoder.
The kit comes with basic wiring instructions. Detailed instructions are available in our ringfield adaptor kit instructions booklet which is available via our website.
