All, Thanks for the information posted on OGR. It’s very helpful.
I need some help or at least guidance.
I have a Santa Fe AC6000 6-28339 with a problem, shorting out when power is applied. I found anytime power was applied to the RAILSOUNDS LITE / DIESEL / LEGACY AC-6000 P/N 691RSL1018 board the engine would short out. I removed all wires leaving this board and isolated the power input cable. When I remove the power to this card, the lights and smoke unit actually start to work.
The bad news is I have to contact Lionel to get a replacement board for $79.00 plus shipping.
When I looked at the board, there is a black surface mounted component next to the power cable connection that has a crack in the top. It is a little less than a ¼” square. There is a number on the component of 104, but I could not gain any more information.
My question is, what is this component and can I replace it myself? I do have a surface mount devise (SMD) rework station. Are there failed boards that I can get and remove working components from?
The other question I need to address is what caused this to fail and make sure any other failed components are replaced, etc. I would not want it to fail again given the price of this board.
Any guidance or suggestions?
