I have a 2011 carbed 500 HO it is showing the hot and check engine right away when key is turned on and it is cold. It also will randomly cut power to the gauge cluster and turn off. Then wont start till gauge cluster gets power again which sometimes takes a long time. Things I have checked... fan works. I changed temp sensor on side of cylinder. Checked fuses. All lights work even when no power to the gauge cluster and it still turns over just wont fire unless LCD screen has power. Also took apart run switch on handlebar and cleaned and reinstalled. Please help me figure this out random no power to gauge cluster and hot/check engine

Check the charging system - high voltage (above 15 volts) will turn off the display to protect it - may just be a failed rec/reg.
