Yes, thanks.  Its quite easy to pull the boiler/cab (body shell) off.  I am unsure about hooking up the second LED for the Mars light on the new boiler front, though.  (sorry -- I'm electronically challenged)  The circuit board under the cab has just one pair of connections for wires to the headlight LED.  Do I hook the Mars light LED up to the same connection?  I know LEDs don't require much current, but would having two in parallel draw too much?

Thanks, Doug

I have two complete stock NKP 765 (no Mars light) Berkshires and want to make one into a different roadnumber without repainting/renumbering.  I recently acquired from Bachmann Parts a NKP 759 Boiler and boiler front (parts only, but with Mars light).  Also a 759 tender shell.  Basically, can I just swap the boilers?

Also, I want to make the 759's Mars light work.  I am new to the Bachmann Berkshires and have not disassembled one yet.  Are the 765 (no Mars light) and 759 (with Mars) electronics boards the same?  Can the stock Bachmann LED for the 759's Mars light just be plugged into the electronics board on a 765?

I am OK with the stock Bachmann appearance of the Mars light for now.

Thanks,
Doug
