04 sportsman 700 no spark

Hello. This is my first post but not my first time on. I have an 04 700 carb. I have no spark. I have the new upgraded ignition system. I also can’t seem to get any power to the coil or the CDI box. I’m lost. I have an E on my display screen. I bought a new battery yesterday cause other one wouldn’t hold a charge. Now the kicker. Ignition switch on I checked my lights, when I turned On the low beams, my starter came on like it was starting the atv with key. Weird I know but true. I took the switch apart cleaned it and put back together and it still does it. Yes my lights work as they should. I’m stumped. Please help. Thanks.
