I need to run an accessory voltage because the main line sometimes the train trots very very slowly. analog regulated and the voltage is well below 8 volts At times. I am also using DC voltage that I concocted my own transformer because I like the train to run very slowly with very little sine wave noise. None the less it runs very nice. sooner or later I will upgrade to an AC legacy unit or something more sophisticated then what I'm using now And prior. I need to run an accessory voltage to the remote switch because of reason above and any time the switch is activated with use of the main lineit has instant voltage drop if below 9 volt, that is the train slows down to a halt and the switch has not enough volts to tirgger itself. ( amps is usually constant to 2-4 amps. ) Which isn't a bother to me I'm just trying to work everything out. the problem is I bought the switch and the manual says I can cut this wire to have an accessory voltage the problem is the wire is so tight and because there are three different wires, the one in the middle as the manual describes that potentially looks like it can be cut. Then two wires on either side of the inductor coils that control the switch. I bought these at a good price for $10 each the man was nice I'm poor I don't want to break it . plus it functions flawlessly at Main Line higher than 8 9 volts. I just recently kind of got into trains, I had some trains when I was younger but I want to really do it up nice if can anyone tell me with their experience and understanding with Lionel products what do I do because this is kind of differing from the instruction manual, slightly. I have attached some photos #Post#: 1011-------------------------------------------------- Re: O-Lionel5121-5122 By: Brendon125 Date: February 7, 2015, 9:21 pm --------------------------------------------------------- I will attach a photo soon momentarily #Post#: 1012-------------------------------------------------- Re: O-Lionel5121-5122 By: Brendon125 Date: February 7, 2015, 11:18 pm --------------------------------------------------------- picture [attachment deleted by admin] #Post#: 1013-------------------------------------------------- Re: O-Lionel5121-5122 By: TrainLarry Date: February 8, 2015, 7:48 pm --------------------------------------------------------- Welcome to the forum! This video produced by Lionel, (HTM) https://www.youtube.com/watch?v=_0McntbmQ9I (HTM) https://www.youtube.com/watch?v=_0McntbmQ9I shows how to modify the switch coils on the 027 switches to accept an external fixed voltage for operation. The relevant part begins just after the 5 minute mark. Larry *****************************************************
