If the ignition switch is bad, would it be able to start with a jump?

I had an intermittent no start problem with my 95. This is the thread on it. Read the first and last post.

99 k3500 won't start
So the battery connection was all green and I knew I had to replace the ends soon. Tonight, after work, I stopped at the Post office, came out, it barely growled like the battery was dead. Tried everything, finally replaced the ends and cleaned the battery right in the parking lot. Dome lights were strong sometimes, and making a weird blinking and clicking noise sometimes when you opened the door...but when you turn the key, everything goes out and it doesn't even try to start. So I figure I wore it down trying, and get a jump start. Fires right up, battery is higher than before because of better connection, I leave it on a while when I get home to charge it. Shut it off and try again, and not even a grrr. WTF? First off, I've never had a dead battery where everthng else worked and it doesn't even try to turn over. So I'm thinking the starter is stuck and sucking juice, or that stupid solenoid wire is loose again (even though both are only a few years old).....or I didn't get the end on tight enough? Can the battery be too weak when it was showing full charge when I shut it off? Now it's a ******** holiday and I gotta work tonight and I'm trapped at home with the **** thing. Any ideas?

thanks crab!
Maybe it's time to change the battery cables themselves, corrision can form inside the insulation, bad grounds cause will cause this
for a test run a jumper cable to a clean ground from the battery and see if it improves
