Battery and Brake Light stays on
Last night I flushed my heater core and I think I shorted something out. After the flush, I drove around for a bit and the Battery and Brake lights came on (see pic)

As Discombobulated suggests, put your multimeter right on the battery posts. You should get about 12.6v with key-off, and about 14.1v with engine-running.
Don't try to diagnose this without a multimeter. They're cheaper than dirt, and they are the only tool that works.

I am going to take off the alt and change the regulator and brushes. It's the OEM ALT so very likely the problem. I'll also take a reading to see if I am on the right track.
Thank you Toyota gurus.

Okay, now what? You could just replace the alternator on the blind. There's a chance that will fix your problem, and if it doesn't, you're only out $125 or so.
Or, you could check the voltage at the alternator output (fat wire). And check the excitation voltage (red wire; should be battery voltage with key-on). If you have no output but do have excitation voltage, most auto parts stores (O'Reilly's, Autozone) will test your alternator "for free." (They want you to buy the replacement there.)
