After finally getting a 5V PS32 board to replace my dead 5V board on my Railking steam loco, I tried positioning the new board and discovered that it is a trifle wider, and the loco shell won't fit over the board anymore. Has anyone tried mounting the 5V PS32 on its side so it can fit into the shell?  Has anyone shaved the plastic frame so the new 5V PS32 board fits into the shell?  Will I be forced to remount the new board in the tender?  I can see redoing the wiring to move the board from the engine to the tender being a messy challenge.

Anyone else deal with this situation?

My engine has a clear plastic sleeve that is molded to the interior of the shell so the shorting to the casting won't be an issue.  I had to remove the plastic carrier for the two PS32 boards so they would fit into the boiler without mounting them sideways.  Now I'm looking at how to make sure the boards don't sag towards each other and the component leads from the top board don't poke into the electrolytic caps on the lower board. I know the heatshrink on the caps is durable, but I'd rather not take that chance of a puncture or wear through after years of vibration.  I think some RTV dots on a cap or two might end up being used to keep the spacing between boards.  The heatsink is under construction and nearly finished.

If the top board has leads that will poke into the caps on the bottom board, trim them off!  I got a bunch of these boards with that issue.  Once you trim these flush, you can then use something like Kapton tape to secure the two boards together.  This is the only two places that the projecting pins endanger something on the lower board.

I'm ready to transfer the wiring connectors to the new 5v PS32 board.  So just to recap before I do anything, there's no connection on the new board for the two pin connector near the diode bridge on the old board with red and black wires, and I should remove the BCS since the new board has a supercap.  Is this correct?

Thanks everyone for your help!
