Hi Folks,
I must firstly thanks all of you who contributed in helping me solve the mysterious problem I was experiencing.
I carried out a lot of the suggested testing & checking and finally replaced one of the SS point motors which seemed suspect to me.
Magic......all went well, perfect running over all track joints etc.
This all stayed good for 3 days, then yesterday started up and all the problem were back!!!!
Stalling at every joint.
I also noticed that following a stall and the unit resetting, the loco drove off on its own until it reached the next stall point and then it moved off again when the unit reset.
Then suddenly all the problem disappeared again and we ran without trouble for another hour.
I am really getting to the end of my tether.
Chris
