"The car made it home but would not turn on"? How is that possible?
Sounds like the generator still isn't working. For future reference, if at all possible, avoid having a generator tested off the engine. Many in-store testers don't do a good job although they can tell whether it's working or not, but there's a lot more to it than that. Given the fact the battery runs down while you're driving, we can assume the charging system isn't working. If you want to verify that, use an inexpensive digital voltmeter to measure the battery voltage. Once it's fully-charged it will measure 12.6 volts. If it's discharged, it will read closer to 12.2 volts. With the engine running, it must read between 13.75 to 14.75 volts. I suspect you're going to find it stays well below 13.75 volts.
There's a number of things that could have been caused by the old generator. First, there should be a yellow wire in the connector. Back-probe through the rubber seal to read it's voltage. You should find full battery voltage there all the time. If you find 0 volts, look for a blown blue 15 amp fuse. If that is okay, measure the voltage on the large bolted-on output wire. With the engine not running, you must find full battery voltage there too. If that is missing, look for a blown very large fuse in the under-hood fuse box. If one is used for that application, it is usually bolted in.
