I'm currently working on transferring the control circuitry from a 30-1183-1 0-8-0 into the camelback I'm building on the carcass of a RK-1111LP 0-8-0. (I got the whole PS2 loco on eBay for less than the cost of a PS2 upgrade kit, so it was a win for me.)
My question: I didn't plan to open up the firebox door to make use of the firebox glow, and room is slightly tighter inside my new body than stock. My concern is this: does the tach reader NEED that light bulb placed in a specific way for the reader to work, or does it need it at all? If I just jam the bulb in anywhere back there will it still operate properly?
