i got this 76 maverick almost a year ago and when i first was starting it up and tinkering with the engine, the engine light adn buzzer went off and only turn off when i take the key out. after some working with it i managed to get it so that the light would turn off, but the buzzer continues to drive me nuts.... nothing ive tried has done anything, including messing with the fuses. im going to go insane if this keeps up... it is quite an annoying sound to listen to.. please help! how do i get it to turn off????
