You're right: there's just enough play for the board to slide forward, up and out. I have the whole thing apart now; the only difference between the front and back is that there seems to be a bit more space between the hex nut and the worm on one end:will play with that a little and see if it helps...Mark in Oregon
I cleaned the trucks when I had them out, although anything is possible. The LED is soldered to the board with long leads reaching out towards the end of the loco...MIO
Good point.So since the motor runs (which it does), and the brush contacts are soldered to this circuit board (which they are) does then that mean the board itself is ok, so it's the LED that's somehow gone bad?Mark in Oregon
There likely is a current-limiting resistor on the circuit board for the factory-installed LED. If you replaced the LED with a regular bulb, then the chances are that it will not light up (because the bulb needs more current than an LED, and the resistor is limiting the current).
OK, just to be clear; this is NOT a decoder we're talking about, as I'm (still) running straight DC.The "board" in question is just the simple factory-installed circuit board which I guess controls the lighting, depending on the direction.I guess if MTL can come through with a replacement, this is all moot; hopefully, I will hear from them this week...
