I bought a 07 sportsman 500ho . it had problems when i got it and was aware ''got it cheap'' Ok he said he had battery /lights/instrument problems then just died NO SPARK at all. from what i am reading it is the PDM/ECM . My question is what is the difference between the PDM/ECM I found a black box in front of the steering collum under plastic that has a large plug that plugs into it. only has 2 screws holding it on. I always thought they were called CDI that shows what i know. anyway i took it off and it has something loose inside of it , it is still sealed up. Is this the part they are talking about? I also have a 08 sportsman can i try the part from it to see if i get spark? or is that a problem. Thank you and sorry for the long questions.Adam

I do have headlights & display, i cycle the key 3 times and no codes, still no spark at all ,thinking it may be the PDM, Can i try the PDM & ECM from my 08 500 ho on my 07 500ho ?
