HO / Faulty Decoder?
May 16, 2010, 10:11:22 PM
Hey All,

     I have a blue box DCC Equipped Chessie GP40 and for some odd reason when I put it on a DCC track the first time, it will not run. When I put it on a DC track, runs like a bat out of heck. When I put it back on the DCC track after running it for a while on DC, it works. Any suggestions?

HO / Bachmann DCC On Board GP40's (Older Models)
April 26, 2010, 10:58:06 AM
Hello,

       I have a bunch of GP40's from the "Blue Box" Bachmann DCC On Board series that I have had for years but neglect to run them because when I try to run them on Digitrax, they will run erratic, as in jerky performance, odd speed differentials, stopping and starting, etc. Cleaned the wheels and contacts, still the same performance. I did some internet research and found that people are removing the capacitors from the motor that are attached between the motor contacts. I have had these things for centuries so I am not worried about voiding any warranties or anything so that is not an issue. Can someone please tell me, do I cut all 3 out and the 2 resistors running to the motor, or just the capacitors? Thanks... Also if anyone knows any websites I could go to for pictures that show what to cut, that would help to!
