Lou,
Seems to be more of an MTH issue than an installation issue.
Really? Why is that?
I popped the tender and locomotive shells and everything is wired correctly according to the PS2 conversion instructions.
Yeah, it looks good now. What happened between the start and the end of the conversion process is a big unknown. Last one in gets the credit - or the blame.
All you know is that the engine was broken when you bought it. You should talk to whoever sold it to you after the the conversion.
