Car won't crank, Guage lights flash, and how do I pull my starter?

Thanks for the replies, everyone, and thanks for the diagrams. as I mentioned earlier, the battery and the connections are good. The interior lights, Tail lights (the headlights are out of the car) the wipers, heater motor, and horn all work with the battery that i have been using. I'm keeping the battery on a float charger. I even tried the battery on my driver car, and the Cuda still won't crank. Even if the battery was low, I should still get a slow crank if the starter is good. I tried jumping the starter with a screwdriver, but it just clicks and doesn't crank the engine. I think I'll pull the starter and have it tested, then I will at least know whether it's hooped or still good.
