do you have resistor plugs in her?i got my dyna last year,and thought it didnt work.sent it back to dyna,they tested it and said it was fine.i could put my old cdi back on and it would run fine.turns out something was up with my coil,bought a new one and it fired right up with the dyna box?i must say there support staff was the best ive run accross in a long time.
