I have a 2015 outty 1000, I’ve never had a problem out of the bike, it’s been parked for two months from not being able to ride. Went to start it today to get it ready to ride tomorrow and the battery was dead. Hooked up battery tender, wouldn’t start, tried jumping it and digital readout shows E and reads transmission signal fault when I press in the brake to start it. Fuel pump kicks on with the key, and solenoid is working. Like I’ve said the bike has never had an issue, need advice on wherected to start looking
