Hi! I am new to the forum but I am hoping to find some helpful information!

I have a fourtrax that I was given. It originally had no spark. I replaced the CDI and the Fuel Pump Relay. I expected it to work and it did not. I do not know what to do at this point. But I do have some leads!

I checked the pulse coil that sends a signal to the CDI. The resistance was .29kohms, so 290ohm. I was told it should be 300 ohms about, so thats good.

I know of an excitation coil, but I cant find it. I do not know how to test it but according to the wiring diagram it could be the problem. Also, could somebody tell me what that does?

Could somebody give me some pointers in the right direction? I know the coil is not getting voltage, and I know that the new parts are good. Any help?
