Testing LM-3

(1/1)

Michael:
Hello Everyone:

I recently purchased several LM-3's. However, I just hardwired two locos without success (I have other locos that have been hardwired with much success). The HC-2 does not find any product. From doing research on this site, I believe there is a way to test the LM without  doing an installation. Do I simply attach the red lead and the black lead (from the LM) to the positive and negative rail? Doing this, will the HC-2 recognize the LM if it is not defective?

Thanks for any help.

That is correct, giving the LM "track power" (which could even be as simple as a non-dead 9v battery btw) will power up the LM, nothing else needs to be connected for it to respond and downloaded to etc.

Now, are the LM's brand new (ie, bought from a retailer) or second hand? if second hand even if the HC still doesn't detect the LM's they may not be faulty but the previous owner could have put a password on them, which can be cleared in following the instructions in the HC manual.

Thank you!  This was quite helpful. I just checked another LM and it is good.
