The YouTube link shows the operation of my Platform on the layout. It works, but...at about the 10 second mark it gets loud and the forklift moves to the awaiting lumber car. It moves to the car and starts to load a piece of lumber. At about the second 23 mark, it stalls and the vibration/motor gets considerably quieter. The sound is similar to the sound in the first 10 seconds of operation before it gets loud and the forklift moves. On the test bench, it worked fine. There was a pause after it unloaded a piece of lumber but then the forklift traveled to the car, loaded another piece of lumber and dropped it off w/o the pause you see at the loading stage in the video. I've done nothing to the platform when I moved it to the layout and the voltage is the same on the layout as on the test bench. Before I open it up, any suggestions, comments, etc. Actually, even if I open it up, is there anything I can actually do? Any idea what I should look for? Thanks.
