2000 kodiak 400 4x4 ultramatic sometimes it will start with the starter and sometimes all I get is a buzzing from the starter solenoid, took it to the shop and he found nothing wrong other than a possible starter relay which he changed, it started and he thought it was fixed so I brought it home, started fine, unloaded and parked it, went back later and same old buzz from the solenoid, did that about three times and started on the fourth, has a new battery, cdi box and starter solenoid but this is driving me batty!
