Athearn Gp15-1 HELP!

[Nathan Jahreis]

Thank You every one.
   Jim, I tried it with the 9v battery (had to use two because they were low). Not any better, still hesitates.  With my mrc tech 4 (200), is it pure dc or is it pulse?  If not, what pack would have the best dc control?

Well now I think it is the decoder because if I run the motor directly from its leads to my transformer (attached to the drive) it runs fine. But with the decoder it runs erratically.  Without the drive attached,  I ran the motor with the decoder it runs fast and slows down and speeds up again.

As I have said, I am thinking that it is either the decoder or my power pack.  However, Athearn has been very cooperative with this whole situation. I am still awaiting Soundtraxx to email me back. I will keep you posted. Thanks for the info on the tech 4.
