hello im new to this forum and in need of help. i am having extreme difficulties figuring out the wiring on this engine. i just picked up a go kart a few days ago and it has a 1997 polaris 400 2 stroke engine and i cannot get spark. after messing with the wiring it ran for about 1-2 minutes then shut off and wouldnt spark and i tried it the next day and it did the same thing, it ran for about a minute then out of nowhere it didnt have spark. and yesterday i was able to get 1 single spark out of it and since then i cant figure it out. i have tried eliminating all wiring except the cdi, voltage regulator, and the coil. which is all i want anyways but i cant figure out how to have it hooked up to each other and work properly. if anyone out there has any idea on how to bypass all the wiring and get some spark please let me know! it will be very very appreciated.
