Motor Over Current in one direction?

<< < (2/2)

Another thought: Bypass your PC Board. If you happen to have a spare 9 pin laying around, hook up track power and motor leads directly to the harness and then plug in your LM. Give it a whack that way. It's possible the problem lies in the motherboard where some logic controlled circuit is not playing happily with the LM.

Worth a shot anyway. It would rule out both the motor and the LM a sources of the issue.

Thanks Gang!

I hope to try all these options later this weekend. This loco has been languishing on the workbench for too long, so I want to get it into service!

Stay tuned.

Hi Gang,

Before I tried anything else (as the install is mostly done), I figured I'd swap out the LM for a verified new LM-3S, just in case. Guess what? No issues with a new LM-3S!

Looks like the LM-2S is buggered. I can't recall if I pulled this from a loco that's been disposed of, or if it's a used one I picked up. I'm guessing the later, especially as the other used one I got was dumping excessive voltage through the speaker when connected. Cooked 2 speakers figuring that one out! It works good for driving my turntable though.

Do you think Tim Ring would work on it (for a fee), or do I just chalk it up to lesson learned? The cost of repair (including postage) might exceed a new LM-3S.

Thoughts?

it's been a while since I sent a module in for repair, but Ring did the repair for what I thought was a reasonable price.
