THAN THE ALTERNATOR WHAT COULD CAUSE MY VOLTAGE TO BE LOW?
2002 Toyota Solara

I have a 2002 toyota solara. The alternator was only putting out 10v. I replaced it with a good used alternator. It is now putting out between 10-12v while idling and 12.2v while revving engine. Other than a faulty alternator, what should I check next? I replaced the battery about 2 months ago.
First check for 12 volts at the generator's output terminal. It should have full battery voltage all the time. If you find 0 volts with the engine off and high voltage with the engine running, look for a blown fuse bolted into the under-hood fuse box.
Next, there must be at least one small wire that has full battery voltage on it. If that is missing, look for a smaller blown fuse.
