What just happened?
Yesterday I take my truck up to the local inspection center, and it checks out just fine. Well today comes and my car will not start, my brake lights dont work, and when i put my left blinker on my right tail light goes out and vise versa, when i put my right blinker on my left tail light goes out. My old man seems to think that it's the alternator, but I am also charging a new battery for the second time this week and that leads me to believe its the alternator *** well. What could be the problem?
Where is the voltage regulator located on a 1970 F-100 300ci engine?

If your battery is losing its charge, it's probably something to do with the charging system. This could be the alternator. I don't know where the voltage regulator is on a 1970 F-100, but in my 1977 F150 it is located at the front next to the radiator on the passenger's side, next to the battery. You will see several connectors going into the side. If you follow these they will make their way back to the alternator. I would suggest you begin by checking all your connections (make sure they are tight and clean), particularly those that lead to and from the alternator. I had a lose alternator power wire that drained by battery. If your connections are all good and you think the alternator is faulty you can usually pull it and have it tested at your an auto parts store. I would have it tested before I assume it is bad. If it checks out okay, I would make sure to clean my connections to the voltage regulator. You can check your connections from the alterator to the regulator to the starter relay for proper voltage with a voltmeter. You can get these at the auto parts store relatively cheap.

You truck has a voltage regulator and they are found near the battery, its a square box about 4in square and if its still a original Ford part it will be about 3in thick and if it is a replacement type it will be about 2in thick. The regulator will also have a 4 wire plug conector and 2 bolts that hold it in place.

It also sounds like you may have two problems at once. Fix the charging problem first. When it's fixed you should be able to put a voltmeter on the battery with the truck off, and get around 12 volts, and then start the truck up and get a higher voltage on the battery with it running. The higher voltage tells you it's charging.
Don't panic if after you get that fixed, your lights still don't work right. If they don't, go to the rear and take the bulbs out of the sockets and clean off the brass part of the bulbs on both sides of the truck. See if this fixes the light problem.
