Why does my 2007 Chevrolet Equinox battery go dead overnight?
Remove negative terminal wire from battery Using a multimeter on DC setting, or a 12v bulb with leads, test between negative battery post and the negative wire you removed, you should see some voltage or light from the bulb, remove each fuse one at a time and check to see if you still have volts or light. When you no longer have volts you have found your bad circuit.
