Likely it is a bad ground. I had the same thing not too long ago and
the ground was the last thing I checked but that was ultimately the
issue.

I assume you mean the ground connection to the starter? In which case
I'll check the ground tomorrow, hopefully that'll pan out. Another
question, what voltage should the battery dip to when starting? I
checked mine, it's at 12.4V before start, ~10V during start, and 14.4V
while running.

I cleaned the chassis ground, but couldn't get at the other ground
connection that's connected to the block by the starter. Anyway, I was
able to get a voltage reading when it doesn't start - even though the
lights really dim, the battery voltage only dropped to 11.66V. Since
I've followed all the lines to the starter and back to the battery, and
the battery voltage is at a sufficient level, I guess there's only the
starter left to replace. Does this sound like a good assumption?
