zedcell Posted June 12, 2020 Share Posted June 12, 2020 (edited) Hi can anyone give me some advice with a problem with a electrofrog point have converted approx 40 peco code 75 points operated via cobalt analogue point motors and everything was running fine. Just recently one started playing up it was ok when set to diverge but loco would stall when set straight. Originally thought it was a bad solder connection to the dropper re-soldered and found locos now stall when set to diverge also. Checked power to points and found the frog area has no power, so i suspected the polarity switch on the cobalt was faulty changed the cobalt motor re-checked all connections and have still no power in the frog area.

RMweb Gold RFS Posted June 12, 2020 RMweb Gold Share Posted June 12, 2020 If the loco was originally OK in one direction then it can't be the Cobalt. Could be the internal wiring under the frog has failed. You might need two dropper wires - one to each side of the frog if that's the case. Have a couple of points like that now on my layout. Do you have a multimeter? In which case see if all 4 parts of the frog rail have continuity to each other. Link to post Share on other sites More sharing options...
zedcell Posted June 12, 2020 Author Share Posted June 12, 2020 Thanks for the reply did check the factory fitted frog wire it looked ok will check that again as i know it is fragile. Checked all 4 parts of the frog area with a bulb no power. Link to post Share on other sites More sharing options...
