I dreaded this would come this but I can not get my new massoth L decoder to work. I’ve combed through many threads and found one similar to my issue but no resolution. He took the loco to a friend’s to program on a piko system.
I installed a Massoth L decoder because I wanted to keep my new LGB loco original and it was plug and play. ALL lights and features are turned off, I’m programming on a programming track. There is NO aftermarket sound or sound to speak of and the accessories switch is set to 0.
Multiple CV are changing together like cv1 short address and cv5 top speed. Also cv2 starting voltage is changing together with cv6 mid voltage. Doesn’t take long to add up how that is frustrating. It is also not allowing me to do a factory reset. Any thoughts or is just not going to be compatible and I need to have someone else program it with their system?
