Garrick,
Thanks for the info, the manual really helps! My background is electrical (I designed, installed and troubleshot aircraft electronic (avionics) systems for around 20 years before getting into sales). The battery is new and works well. The starter won’t even turn when I jump it with the car. I suspect that the brush leads may have frayed or broken and are shorting out to the case. I think I will bite the bullet and pick up a brush set and try that tonight…
