I have to replace my rechargable battery pack in my MTH Hudson 70-3001-1 It is the 1st run of Hudson's. The sound cuts out for a second randomly. I thought it was a broken wire, but my local dealer said it is most likely the battery going bad. I did not buy his answer as 1st. I figured that it is a broken wire/connection. So went looking for one by powering it up as usual on DCS, and wiggled wires around. The sound did not cut out at all. The battery voltage measures fine with engine off the track. So I am going to replace the battery. Has anyone had a Hudson apart?
