Scratching my head on this one. I parked a couple days ago and now nothing works-- no dash/hazard lights, cranking sounds, nothing. Tried jumping the battery, no luck.

The cables to the terminal look fine. Everything seems to be connected.

Any ideas?

Battery fuse? Another fuse?

 

The first thing I would suspect is corrosion between the battery positive terminal and the battery cable. The corrosion could be there but not readily observable. I would pull both battery cables off and clean the battery posts and inside both battery cable ends and then reinstall the cables. If power is not restored, use a multimeter and check for battery voltage. You need to be in the 12-13 volt range. If that checks out, look for a good ground from the neg side battery cable to where it bolts to the body to ground it. If still no power. tug a little on the positive battery cable and make sure the connection to the starter is tight.

Remember that if you left your headlights on for instance, over 2 days you may have drained the battery down so far in power, that a jump start may not work, or you may have pushed an already weak battery into failure ie dead cells. Report back with your findings and we can go from there.
