Rich,

Start with a simple test, take the starter to your local Auto Zone/NAPA, they should have a test bench for this. Have them spin it for you, and make sure they check the amp draw. Could very well be a starter problem, 3 weeks old or not. A lot of the re-man starters they sell now are really junk. I would try a high tourqe/gear reduction starter.

Good luck!
