This is a new post on my MTH 30-1152-1 RailKing Reading Crusader.
I replaced the older battery with a BCR. The locomotive seems to run fine.
The main issue now is intermittent chuffing. To get the chuffing working, I have to supply a higher voltage. When I throttle down, the chuff either stops or stutters. I checked the wiring and can’t see anything loose.
Horn and bell work fine. I figured I’d let the experts here have a crack before I take her in. This is original protosound.
