bump the old one, it tells something of a story as so to help you out more. starting a NEW thread wont get you better help.

wish i did.

but im will to bet dollars to donuts these fuses have nothing to do with your over night power loss. lots of good info was given as to find whats drawing power, but all you care about is these 2 fuses.

I answered your question. They control everything. Pull them and you wont have power to anything. It is split into two circuits. Batt 1 will run half and Batt 2 will run the other half. The spark test you're doing is not going to tell you much. Disconnect the positive or negative battery cable and connect a DMM in amperage mode to the cable and battery post. See what your draw is. If it's over 30-50 milliamps, it's too much. (.03-.05 amps) Especially if it's not a daily driver. Start pulling fuses and see what fuse drops the amperage. If you want to know exactly what each batt fuse controls, unplug one and turn the key. Test every fuse for power on both sides. Write down which fuses have power. Now, repeat for the other batt fuse.
