I should have. I got it taken apart, cut the black wire, and put it on the track. Address 3, it starts up, a bit of lights, smoke stack works, start to move it forward, then a nice bzzzztttt sound while the lights flicker, and then it's dead. Likely, completely dead now. I get no response to any command on address 3. Is there something I should look for? I don't see any broken wires, don't smell or see any electrical damage on the logic board. What might I have done?
