Speaker Healthcheck?

    One of my locomotives with pre-installed dcc/sound stopped making it (sound) a few weeks ago.

    Initially I blamed the decoder, although all motor and light functions were still working. To determine for sure if that was the case, I switched decoders from an identical locomotive and installed it on the faulty one - still no sound. Alternatively, I took what I thought was the faulty decoder and installed it in the locomotive that had no problems - it still made sound.

    This is obviously not a decoder problem and most likely is a speaker fault. How do I determine if the speaker is good or bad? I'm assuming the latter, but want to do some tests to confirm. I just don't know how!

    First thing that comes to mind is to take it out of the loco, and connect it to a stereo, at very low volume.

    Thanks Gary. Maybe I'll use one of the kid's walkman's for reduced output.

    I was looking at one of the retailers web sites- speakers are rated in impedance (ohms). Can this be measured with a multimeter across the leads? In case I need to replace the speaker.
