So the other day I followed the steps to charge and run my Protosound 1 Southern F3 ABA. Tonight I had it going around the track. Shut it off and now when I power it back on (this was over an hour ago that it was running and when it shut off I heard the boards shut down.) It powers up and makes two clings buy will not move. If I shut down I get a ding and if I hit the whistle I get a ding.
What does this mean and what do I, or can I even do?
