MU LM-3S and LM-2

(1/3) > >>

ON28:
Are there any issues consisting a loco with an LM-3S and another with an LM -2? Separately, do I have to add resistors if I swap out bulbs for LEDs with either the LM-3 or -2, or are they configured to accommodate LEDs without a resistor? Thanks!

nodcc4me:
As long as you set the maximum current for both locos there should be no consist conflicts.


If you are replacing older incandescent  bulbs with led’s you will need resistors.

KPack:
What Al said.

Any LM will MU just fine with any other.  I have LM-1, LM-2, and LM-3 modules and all play well together.

Yes, you need resistors for LED's.  I use 1/4 watt, 1000 Ohm resistors for my LEDs.

ON28:
Thanks for that. Maybe something for Tim to consider with all the locos factory-equipped with LEDs.

Double-edged sword. How would one go about "un-resistoring" an LM if they are using lamps? It's easy to drop the current, challenging to up it.
