My PS1 Class A has an issue where there is no apparent battery power getting into the system. I am running with a conventional Lionel transformer. The locomotive operates properly with all lights, sounds, and motion when track power is applied, but the sound completely stops and you can hear the power disrupt from the speaker when changing direction or turning off the power completely, ie no shut down sequence/ bell. I've tried replacing the battery, using a BCR, and using a different 9v connector wire that attaches to the board. It's running like there is no battery at all. One other quirk is that it always seems to go into reverse rather than forward when first changing out of neutral at initial start up. Any advice would be greatly appreciated.
