I have looked into this before, but i am still having a problem, i have now changed my points and put in a seep P1 motor to the two points see enclosed photos, i attached the points to the layout with ins, fishplates as per the photo, but as soon as i put a loco over the track it tripped out. The two points are wired into the bus bar , and when you put a loco onto them without being attached to the layout no problem . I have even changed the two wires around D and E on the seep motor but no difference .any info will be of great help, many thanks.
