Last year I bought two Intermountain FP-7's, put them on the track to be sure they worked and they did. I put them up so that I could work on other railroad projects.
I took both out today to assign numbers etc. When I put one on the track and tried it out the sound would come on and go through transition etc as I worked the throttle but the loco would not move. I tryed the second unit and the same thing. Bells, horn, lights work.
The manual suggest re-setting to factory default settings. I used my MRC Prodigy Advance to do this. I than set the addresses to the Reading Road numbers I wanted. The new address is programed but the loco still will not move and the sounds and lights are still going strong.
I do not suspect anything mechanical as both units have the same problem. I have fiddled with the F9 shut down and F6 start up but this does no good.
I was thinking power on the program track was insufficient but than I was able to program the new road numbers so I don't think it is program track power which I have heard can be a problem.
I am wondering if the magnet for the reed switch has done something. The boxes are thin and stacking them together maybe there was enough magnetic force to reset something. One magnet was attached to the front coupler, the other magnet was on the roof near the cab of the other. I would think the re-set to default values would have taken care of this.
Before I send them in for repair can someone tell me what they think may be the issue.

Dan,
I am in program mode only for programming not for running. I am in correct mode when running or in this case trying to run the FP 7's.
By the way these are QSI sound equipped.

Check CV29 it should be 34 or 38 for a 4 digits road number.
To reset your QSI loco do the following:
Set CV49 = 128
Set CV50 = 255
Set CV56 = 113
As the engine resets, you will hear 3 toots. Test out the loco using address3.
Reprogram the road number and don't forget to set CV29 to 34 or 38.
