Coil Question

91 Bronco still having spark problems. I tested the coil, and I was trying to find out how much voltage should be coming out of it. Right now, I get 12v in and 12v out with just the key on. When I try to start it, the input and output both drop to 10v. I thought the coil was supposed to boost you voltage?
If I pull a plug, and plug it in to the coil wire, I get no spark while trying to start the engine. However sometimes just as I stop turning over the engine, I get a spark right at the last second.
Any Ideas?
