Cory,

Use a good DVM, like a Fluke 75. Use clip leads to connect it between
the stud on the starter and the starter frame. Crank (mixture at
cutoff), and read the voltmeter.

If your voltage drops below 8V, find out why.

Repeat the test with the voltmeter leads connected directly to the
positive and negative poles of the battery. If the battery voltage
drops below about 10V, then replace the battery. If the battery voltage
holds above 10V, then use the voltmeter to do a binary search to find
where the big voltage drop is. Fix that.

Dont overlook that the voltage drop could be across the ground path
between the battery neagive pole and the starter frame.

Personally, I prefer the flooded cell batteries...
