You alternator is dead.

And it drained your battery.

You will need your battery charged (since its dead) or a new one if you killed it, and a new alternator.

The charging and brake light is toyotas built in "stuff aint working" system

I had this problem earlier in the week. Swapping an alternator is not a big deal. I squeezed mine between the frame and the lower radiator hose and all was well. Get thee a new alt and you'll be rollin' again.

You dont need to replace your alt. More times than none you just need a set of brushes. Easy fix. Like Deathcougar said, you will probably need a battery too since yours was drained

For most guys, i say just do the whole alternator. I know its prolly just a set of brushes. But its just 100x easier to replace the unit as a whole than to try rebuilding it. You can find a good used one at a local wrecking yard for a great price, and it means much less down time instead of screwing with fixing the old one.

My $.02

if you know anything about how brushes etc. work then you can replace the old brushes in under an hour. I am also a hobbiest so I know exactly what I am doing with electric motors. The difference is you don't have to go scrounging for the right alternator in a junkyard and hope the one you find isn't too rusted to use. Brushes can be had at most auto parts stores.
