Hey Guys - Thanks for all your previous posts to help me with this project. I have a 68 firebird and I am trying to figure out if I have a draw in my electrical system. I have to charge my battery every time I let the car sit for a day or two. I am not sure if it's a bad battery or a draw in the system. The reason being that whenever I hook the battery up to the charger I have a relay that starts buzzing really loud but then eventually stops after a couple minutes of charging. It's the relay on the very inside of the front near the drivers side headlight (on the backside of course) opposite of the battery. Does this indicate a draw from a bad relay? Is this the horn relay? Thanks guys!
