Chrissaf Posted March 18, 2019 Share Posted March 18, 2019 hibe aware of the variations of the ringfield ,the one which uses a screw to provide a circuit to the chassis from the motor will need isolating from the decoder ,after that it is pretty straight forward.give the motor a good service and ensure it is a good runner in dc mode .if possible do a stall test with an ammeter .use a decoder rated at 1 amp .

Chrissaf Posted March 18, 2019 Share Posted March 18, 2019 Hi Everyone I have an older Cadbury Castle and I would like to convert it to DCC mine has a ringfield motor. Has anyone hard wired a chip to this type of motor is it easy to do? Thank you in advance for any advice. Link to comment Share on other sites More sharing options...
96RAF Posted March 18, 2019 Share Posted March 18, 2019 Go to Brian Lamberts site, DCC section where he covers most if not all of the ringfield variants...Scroll down this page a long way ...https://www.brian-lambert.co.uk/DCC_Page_1.html Link to comment Share on other sites More sharing options...
Fishmanoz Posted March 18, 2019 Share Posted March 18, 2019 Adding to Jane’s, you need to check you have an open circuit between that LH motor brush and chassis with a multimeter on resistance range or a short circuit tester. Rob’s Brian Lambert reference should also allow you to identify what ringfield type you have so whether the LH brush is isolated from chassis or not. All that said, my memory is that these Castles have the brush isolated and the motor in reasonable condition can be handled by the 500mA 8249 decoder. But always worth checking stall current to make sure. Link to comment Share on other sites More sharing options...
