Once you get your multimeter, I suggest you check the voltage at the battery with the engine running. It should be around 13 volts. If it is much higher, maybe your alternator has gone crazy and pumping too much current to the battery.
PS - The PS fuse is a 10 amp fuse in position # under the dash (at least on my 2013 FRS).
I hope you get it figured out.
(maybe it's just me, but I can't see your pictures - Google has a very old e-mail (g-mail) for me and no way can I remember the password - yes, I tried 1234, but it ain't THAT old)
