Hi, new member here. Sorry if this has been covered in another thread.
My 2004.5 Sportsman 500 HO is not charging the battery. My ECM has been updated after the recall with the new SurePower module, I have a new battery, it will start and run fine (although the battery drains quickly), but no charging voltage is going to the battery. The stator has been checked and all three legs are putting out the right AC voltage at the proper rpms.
I am keeping the new battery charged using a Battery Tender. Starting voltage only drops to 12.3, so I know the battery is solid.
Any ideas on what else I can check?
