Hey all,
Im new here, so I figure i’ll start out with a problem [;)] Anyways, You guys probably know about the newest run of the Athearn AMD-103’s. Limited, and Made for Walthers. I got one for Christmas, and it ran fine for about a month, but then it started making a horrible noise. Like a grinding noise. It will now run for a few minutes, and seize up for an hour, just to repeat again. 
Any help is greatly appreciated. THANKS!
