I am working on a MTH Daylight Special(RailKing 30-1119-1?) steam engine that was produced in 96 or 97 and has the electronic horn only, no other sounds, no battery and not PS-1. The engine only runs in reverse. It will run N-N-R-N-R. The boards are two boards sandwiched together, like PS1 but no battery and only four pins connecting the two boards. The speaker is an 8 ohm speaker that does ohm out around 9 ohms. The horn will blow almost constantly and not very well. Maybe the speaker is bad too. I checked the boards and did not see any burn marks or blistered capacitors, everything looks okay. I have no way of checking the boards and do not know what does what. The reverse unit is obviously working but it won't go in forward. If anyone has any ideas or suggestions I would really appreciate it. I thought I could reverse the wires on the motor so it will at least run in forward. Thanks in advance for any advice.
