Atlas O Scale F7 (2 rail) Install

(1/1)

TJMac:
My first RailPro install....couldn't have picked an easier engine....so much room.

1. Remove all electronics and rewire the four-wire truck plugs to match type and output
2. Build harness to connect trucks to LM-4S-G
3. Build second harness to connect Atlas speaker and existing lights to LM-4S-G
4. Create custom LM mount using Fusion360 and 3D print

All my engines will be wired exactly the same so that electric components can be interchangeable regardless of brand/type

JRad:
Does your O Scale F7 draw so much current that the G scale board is required?

TJMac:
Full load current for this F7 is 1370mA. I only know that means heat won't be an issue according to Ring....no idea if that also means I could have used an LM-3S instead. I have a couple Red Caboose GP9s that were converted to NWSL Stanton drives, and I'd bet money I can use the LM-3S as when I did the full load current test on one of them it only read 650mA.
