THEN THIS SHOULD BLOW A FUSE SOMEWHERE NOT MELT & BURN UP
Some might blow a fuse, most do not.

IS IT COMMON TO RUN 2 DAYS BEFORE OVERLOADING?
Yes!
One thing I haven't mentioned is the mystery seizing up...runs fine for a day or two and then all of a sudden locks up and doesn't work.....some work again when cooled an fail again after a few days = bad compressor.

CAN I CHECK THE CURRENT WITHOUT NEW STARTER & CAPACITOR COMPONENTS?
Usually, but for now just seeing if the compressor is getting power or not is the place to start.

CAPS ARE EASIER TO READ...NOT YELLING
That's ok....it is actually harder to read for me.
