I have a 2010 rancher 420 that I have recently been having starting issues. When I turn my key on my lights on the instrument cluster all start blinking really fast and I can here the relay under the seat is clicking really fast. Then if I hit the start button sometimes it will start and sometimes won’t. If it starts it runs like normal but if I shut it off it still has the same problem. I replaced the relay and starter solenoid but it didn’t help. I also tried my neighbors battery from his rancher and it still does the same thing. Any other suggestions before I take it to the dealership.
