I would say that your charging system is not working at all.When you start the sled use a multi-tester to check the battery when it's running.It should be at around 13.5 when the sled is running at 3000 RPM according to my manual.If not you have a problem.Check the fuse in the box above the EFI unit .There are 3 fuses there.Its the one all the way to the right it is labeled charging system.Make sure that the fuse is good.
