Need help with old MTH GG1

I had a MTH scalee green GG1 think it was a 1998 catalog.

Had the same problem

Put it away for two years and it would not run.

The LHS installed a BCR and have had no problems since.

But it sounds like you may have lost a board or something like a broken wire.

KC,

   Do as Charlie advises, install the BCR put the QSI GG1 engine on the track under power for 10 minutes, more than likely you will get your engine to start, if not the board will need replaced.

Hi Guys,

Thanks for your input, but I am confused - this engine doesn't use a battery, does it?  Or is something built into the QSI reverse unit?  I can't see where a BCR would be installed.

OKHIKER,

Thanks for the input.  Sounds logical that it could be contaminated somehow.  I'll clean up what I can and see if that helps.  Thanks again to everyone.

Success!  Thanks to all for the advice.  I loosened everything, cleaned what I could, and put everything back together.  Works smooth as silk now.  Don't know what the exact problem was - dirt, corrosion? I guess I need to run my engines more often.  Thanks again.

Pins in connections like the boards have can oxidize over time even while connected.

Removing and re-seating them a couple times will scrape through this and achieve function.

Rubbing the pins with a pencil eraser will clean them very well. (Work experience here on old Industrial control units.)

Running the engines regularly helps avoid this as the vibration from running down the track seems to keep the oxidation scrubbed through.

This is similar on all electronics, not just trains.

Swanko,

          Glad your GG1 is back in operation.  Something must have worked! Whatever it was!
