I have a train that I'm upgrading to PS2 and replacing the blueish LEDs to warm white. This is the head light circuit board and attaches to the ditch light circuit board that has a resistor in line that measures about 73ohms. I trace the path on this one, and it divides into two for the headlights connected to D1 and D2. Each circuit has another resistor the way I'm seeing it on this board and each is another measuring 73 ohms in R1 and R2 position on this board. Then there is something in the circuit labeled C1 that appears to me to bridge across the pos and neg?? I can't figure out what that would be?
I'm not an electrical guy so I got stumped on why something would be across the wires? bleed off stray current? protection? I like to remove stuff that may harm the board's outputs. I think I'll remove it all and wire directly. Just wondering. hard to focus on the tiny component.
