You need to check the main fuse first (not sure if this is the Honda name for it?)

Look inside the fusebox again, there is a main fuse, probably rated around 80-100 amps. It will be secured to the incoming positive battery lead by phillips head screws. This is the first line of defense against electrical shorts. You might need to look more closely, the main fuses appear differently than the smaller ones. It is a little tougher to tell they're "blown" unless you have seen one before. In a pinch you could substitute a 60 or 80 amp unit from an auto parts store until you can find the proper one. The parts store never seem to have the higher rated units on the shelf.

If the main fuse is blown, you'll have no power to anything, it disconnects the battery from the fusebox.

 

Did you have the (+) cable on the battery post & the (-) cable on a chassis or engine ground? If so, then the fuse won't protect you. Possibly one or the other end of the ground cable is burned. There's 2 ground cables, one from the battery to the car body, other from the body to the engine. So there's 4 cable-ends to check. On the 4-cyl that body-engine cable is located at the left-side engine mount, but I'm not sure about the V-6.
