I got a MTH 30-2115-1 Sante Fe Dash-8 engine for Christmas. I was supposedly new from e-bay and looked like it. We ran it on the layout and it did fine, but it didn't have a lot of runtime. I packed it back up in it's box to bring to work. The front coupler was broken off in the box and I wanted to get a second opinion. We just looked at in and did some planning for extra detailing. We took it out of the box a couple of days later and it stopped working. When you give it power the sounds start and as soon as you put in forward the breaker popped. I checked everything and didn't see any problems. We tried it on another layout - a simple realtrax circle and it did the same thing. I opened it up and didn't see any loose wires, nothing jumped out at me. Put it back together and it worked a little better. It started moving went a track length or two and popped the breaker again. I tried it again this morning and it ran around the layout but I noticed the back truck was sparking a lot over the switches. When I picked up the engine I noticed the back pickup roller was very hot.
Help?
