From my understanding from 1k or 1000ohms ?resistors and under is drawing to ?much current ,which is could be problematic with decoder boards ?. I have several decoders that are using ?470 - 620 ?ohms ?. I was told these were average for esu ,soundtraxx
older boards so I will change them to 1-3k ohms if this is correct. ?What I¡¯am doing now is attaching leds to my tortoises so I don¡¯t have to see what switch is thrown on the layout ?and look at the panel instead so what I have is a 100.000 ohm resistor which
is a 10 k I think ?which works great. ?so I was going in the wrong direction ?with resistance ?. Thanks learned something new. Pease correct me if wrong.
