if the battery is not bad and fully charged, remove the positive cable. Touch it to the positive post slowly. If if sparks, you have a load on it. remove the fuses one at a time and try the cable on the post each time until you get no spark. The fuse you've pulled has the load on it. Trace the citcuit until you find what it is. example, the ign fuse. It may be the alternator is staying hot.
A short in the wiring.

A dead cell in the battery will cause it to loose it's charge overnight. The only fix is to replace the battery. Any light that is staying on will drain the battery. Also a stuck relay will drain the battery.

An axiom for virtually all electrical problems, found to be especially true for those of this type: It's a bad ground connection.
No, it can cause you to use and excesive amount of fuel but it will not effect the battery.
When the battery light is on. That means your charging system isn't working. You should have your system check. It will drain your battery.
If no accessories have been added that are draining the battery it is probably the voltage regulator . The voltage regulator will short out creating an open circuit , and the battery will drain back through it .
Have you tested the actual battery ? For a battery to run down that quickly means a huge power drain somewhere or a bad battery.
