So, I got the shell off. I dissassembled the smoke unit, and checked the plunger. I lubed up the smoke piston/plunger and tested. It moves freely. When I reassembled, placed on my main track, fired it up, same thing; music, lights, work fine. When I try to move it forward or backwards, the amperage draw spikes up to 5.5 amps! Why would it do that? Does that mean the motor is fried or hung up somehow? I didn't see anything wrong with it.
