Testing the Coil on a Yamaha G16 Golf Cart

Hi, I'm a new member tonight!
I'm working on a 2001 Yamaha G16 gas golf cart and need help testing the coil. I just rebuilt the engine, the guy who owned it before me put the rear in the air and floored it until the rod gave out. So I got it as a basket case. I was checking the coil (which he used to try to pry the flywheel off) and once I straightened the plates on the coil, I set the gap to .018 and had no wire on the 1/4 spade and turn the flywheel to check spark and nothing happened after many tries. I reluctantly ordered a new one thinking this one is shot, installed the new and the same thing happens, no spark. Are these coils fed a 12 volt charge to work? I was checking the resistance on the coil and they are both even (new and old) I had the understanding that these coils needed to be open to ignite but It looks like this idea is wrong. Do they need 12 volts?

I found a cart repair shop in Pen Yann NY who was realy a great guy and shared helpful information with me. The way to test a coil is go from the blue wire (coil kill lead) and ground you should get about 1.0 ohm, set ohm meter to K (1000) , test coil lead and coil kill lead (or blue wire you should get 9 to 12k ohms. In thinking mine was bad, I bought a new coil from LVS Sales and recieved one that was no good (tested no good), So I put the original one back on and it worked (much to my surprise). Hope this helps someone!
