Guess who's back

Coils are cheap. I'm sorry I didn't catch that tidbit on the first time around. You should have your ign hot (blue wire) attached to one side the ballast, on the other side should be between 9.5 & 10 volts going towards your coil. At the coil should be a black wire I believe with 12 volts but only in crank. If you have 12 @the coil all the time it will fail in short order. Check your voltages . If you have access to a "test" spark controller, you may wanna give that a try. If it's not vacuum, not fuel and crank to cam timing is dead nuts the dwell could be screwed up. I,ve had manifolds glowing white due to faulty dwell . Good luck
