P0603 So this must be just from leaving the battery disconnected a few days which is what I've been doing out of fear that I have some parasitic draw or god knows what at this point.

As stated above, it wouldn't start after 3 days of sitting with avg temps in the 110-120 degree range outside (car is garaged).

Tester says the charging system: battery, starter draw, alternator are fine...

Here's my plan: Leave battery connected, test it each day, and go from there.
