    I have been chasing a problem with charging the battery. I have changed the battery, alternator and have a new regulator to install. What I noticed when I was changing the alternator though was that a buzzing noise was coming from the battery about every two minutes. I had the ground off the battery and the positive cable on. Any idea what would cause that buzz???? I am also thinking that this would be a draw on the battery when the key is off.

    My only ideas are the radio and the regulator. The regulator will be replaced one of these nights and I'm moving it to a garage this weekend so I can work on it inside. I'll pull the radio and check all the grounds that another post on this site mentioned. After that would be to isolate the circuit and solve it.

    id recomend grabbing a test light and figure out what is drawing juice from your battery. it may take a while, but you will be able to trace it down. start at the battery, remove the positve lead, and connect the test light between the postive on the battery and the positive lead. if the light comes on then it is drawing juice somewhere further in the system. id check the alternator next using the same method, if it doesnt light up it means the circuit is good. sorry if i bored you, my $.02

    Gas bubbles often accumulate on the battery's plates during usage. The buzzing sound you're hearing is more than likely the release of many of these tiny little bubbles.

    Would the buzz be only every minute or so and it is a new battery? I plan on testing all the electrical leads this weekend. I can't think of anything that would draw intermitenly?????
