My warrior is having trouble starting. Neutral light comes on and when I press start I can hear a buzzing coming from a relay that is under the rear fender. Sometimes if I wiggle some of the battery or relay wires it starts but it is getting worse. I took all the wires off and cleanded everything with electrical cleaner and it still failed. I also checked a fuse that was back by the relay and it looks good. Could I simply need a new relay or do I have bigger problems like my start switch/starter?
