Installed and tested v5 decoders. Seemed to be working ok. Changed the speakers over, now the deciders are misbehaving. They only respond in6 14 speed steps - anything above step 14 brings the loco to a halt. The sound function buttons
have gone haywire. Pressing on any function button makes a random selection of sounds lock on.
I've tried a decoder reset; tried reprogramming to 128 speed steps; tried restarting jmri; tried restarting the sprog controller and decoder pro. Nothing seems to help.?
