Ok, so my alternator went bad causing me all kinds of head aches. Truck ran liked it had jumped timing because the voltage was to low. It has a Advance Auto rebuilt alternator on it so I took it and swapped it under warrenty. My new one works fine while running but while its sitting with the key off the alternator is making a buzzing/humming type noise and within 12 hours my battery is dead. If I unplug the brown wire from the top the noise stops and the battery is fine. As of now I only have a head unit and a power inverter hooked up, the inverter doesnt even have a fuse in the fuse holder though. WTF is going on? Did I get a bad one?
