Not sure quite what youre asking. Do you want to check the fuse? Is that what youre asking? How do I check a fuse. Normally you can see the wire through the middle to give a quick indication. This wont always mean the fuse is ok. The best way is to use a multimeter and measure the resistance of the fuse. It should be really low, ideally 0 ohms.

Replaced two batteries already-something still drawing power from batteries what do you do first?
You have to find out what is drawing power. Look at all interior lights, glove box, trunk, under hood, all lights including brake lights. If none of them are on it may be a relay such as a power window or door lock relay that is stuck. Can also be one of the p/w switches stuck in the up position. Test them all to see. If you are unable to find it in this manner, then start by removing fuses. Once you get to the circuit that is drawing power you will know by the spark when you remove the fuse.
