The battery was hooked up incorrectly and sparked. Smoked the voltage regulator. Replaced the voltage regulator. Have 12.89VDC at battery, but no voltage at fuse box. Lights, horn, or nothing else works. Is there an in line fuse? If so, where would it be located. If not, Help!!

Could have damaged regulator. When the car is running have you checked the voltage at battery terminals. If battery is charging it should be around 14 volts. If around 12 your charging system is fubar.
Meanwhile if you have to charge the car every day then something in the car is draining the battery, Using an ammeter you need to track it down, Hook it up to battery and pull fuse out one at a time till the drain goes down. That isolates the circuit with the problem.
you must RUN the scanner/computer for easy diagnostic, and fix it. Remember the electronic vehicle is very complicated, You can have some faulty: PCM+ignition coil+BCM+sensor+etc. see the diagram attached. God bless you
You already took #1 off the list. The national auto parts chains (AutoZone, Pep Boys, and Advance Auto Parts) will hook up a diagnostic tool to your car to perform a Charging System diagnosis for free - its an easy way to exonerate & differentially diagnose your Alternator/Battery/Voltage Regulator.

nissan was always junk in my mind but lets see if we can figure it out repalce the red cable case its smoked and will give you problems latter on down the road second pop your fuse boxes and start pulling and testing the fuses to find burnded one's replace any you find bad if that does nothing you'll need to roll your sleeves up get a lil dirty make sure you look over the black cable/neg to make sure its not smoked either if that dont happen you'll probly wnat to take it to the shop of your choice and have them test it to see how bad the smoke out was chances are it not that bad good luck smokey.
