I have a mule 1000 and am getting a warning buzzer at various times. Nothing consistant. It is intermittant and very brief. I disconnected the speedometer cable, started the mule and still get it only more pronounced. Can you eleminate the speed sensor by opening the Light Green wire. I have checked for continuity in the ground side of the connector for the speedometer and it is good. I also have about 6V on the light green wire coming from the igniter with the sw on and the motor not running. When the buzzer sounds I loose this voltage. Any help would be appreciated.
