Having got my N scale layout up and running with a Lenz Set 100 in control, if I get a short then any loco fitted with a Lenz mini-gold decoder (via a NEM651 socket) sits there with the lights flashing once the short is reset. The locos with TCS M1s don't seem bothered! I cannot find a simple way of resetting them but assume there must be one. If I lift the loco off the track and replace it, it's fine but not ideal to say the least.
Anyone able to give me a simple pointer as to what is happening here please and a better way of resolving the reset?
