Big Blue has inspired some purchases

Well, good news, bad news.

Got humpty dumpty together with my Digitrax DN136 decoder installed - chassis only.  Decided to check out the function of the motor and gearing before I get too far down the road.  Put the chassis on my programming track and addressed the locomotive successfully.  That meant I was getting good power to the decoder.

Stuck it on the main track and was able to operate forward and reverse starting at low speed.  As I was progressing through the speed range the locomotive suddenly stopped and all I got was some buzzing from the decoder.  Back to the drawing board in order to figure out a "why" - I'm guessing that I may have a sneak circuit even though I believed I'd properly isolated the motor brush contacts.  Maybe contact between the flywheel and chassis?  I wouldn't think that would backfeed the motor, but I may be wrong.  I've ordered a new decoder and will send back the old one to Digitrax.
