Bad spark?

Hi Michael i delete the ballast resistor allready i also tried directly 12volt from the battery still a bad spark, i also made a new negative cable from my battery to the negative cable and to the chassy, but my plus cable is still 40 years old i will change that one too and i also will try a good optima battery, my friend will help me this week im sure that something with the main cables or the battery is wrong cause i installed everything new, the distributor just have 3 cables one goes to the negative of coil one to positive of the coil and one to ground, i also tried this one directly to my battery, if this still dont help a devil is inside and i will call judas priest8)
