ok. So I will remove the tach, and take it for a drive around the neighborhood tomorrow... hope for it to die on me and replace more things 1 part at a time. :thumbsup:
Holly **** you do NOT listen! Red to power, black to ground, white or yellow for light and green to coil negative. You do NOT have to remove the tach. Just wire it up right. REMOVE the green from ground. That's all you need to do. You'll still have the tach and that will FIX your coil problem....although it probably is damaged. That's like cuttin your leg off because you stump your toe.
