Strange problem - putting a Loksound Select Micro decoder into a Kato n scale MP36PH loco. The sound is working well as are the light outputs and I'm able to control these with function buttons (JMRI throttle) without difficulty. As soon as I apply some throttle, the sound ramps up, but after about 3 seconds it cuts out and my Sprog3 is flashing rapidly indicating a short-circuit. The loco never moves. The short-circuit lasts for about 1/2 second, and then 3 seconds later it does the same thing. When I place the throttle in stop, everything is fine and I'm able to reset the sound and lights. I thought it might be a short circuit with the motor in the loco, so I detached the gray motor lead from the loco, but this didn't change the results - still 3 seconds to a 1/2 second short-circuit etc. In the process of trying a few things, I accidentally touched an alligator clip to the motor solder connection where the gray wire was and bridged to the chassis - the loco lurched some, so power is going through the red wire in the decoder to the motor and back to the track on the other side. I don't think this means, anything other than the motor works, but you never know. I'm using DecoderPro and do not have a Lokprogrammer. This is my first attempt to do my own decoder install (my only other loco is a BLI which runs fine on this layout). I've tried DecoderPro in both Sprog and Sprog Command Station modes with no difference. Any debugging suggestions? Thanks!
