Lionel Odyssey engine Cab #5444 Hudson. Recently received a engine that was stored away couple of years. Put it on the 072 track. it ran very slow, both directions. I thought someone had locked it into a slow speed. I preceded to unlock it and than set a faster speed. It ran ok for 10 minutes When I shut it off it went back to the slow speed. I reset the speed again. Shut power off When I started up again I still had slow speed but I also lost lost sound,smoke I still had lights.
Things I tried checked all plugs & wires Pulled the three boards & reset them. pulled the 2 chips & reset them. I now have lights, bell & whistle, forward & reverse (slow speed) I noticed on start up it goes forward without pausing Also when I reinstalled the chips I matched the angled edge with the one on the PCB board is there a right or wrong way other than that Is there a way to test the sound board. possibly changing the chips from a different engine I do this on a MTH PS1 engine when I think the chip is bad.
I appreciate any input
