well, when I had a big starter problem, I figured it out after messing with it for a little while this way. I took my jumper cables, and hooked one to the positive on the battery (1), and went right to where the starter wire exist on the starter it self(#7). I tapped the jumper and got a spark. I had a bad starter. One with an internal short. This was hard on my battery and my solenoid because of it shorting out when I hit the key. If all else fails create a new ground to the starter also. This works well for me, because it can tell you if you have a bad starter wire. Good luck.
