What year ? What dizzy ? Do you have points ?

points 1977 yr

What shape are the points in & are they opening & gapped correctly ? Stock I 'think' s/b 20 or 21. I may be wrong on those #'s.

What dizzy ?

John

Edit: Also how about your condensor...good ?

points are new . the wire out of the coil is getting no spark . put spark plug wire against block no spark

Stock igniters very rarely go bad.

I would look at gap, condensor and did you put the rotor back in ? I have forgotten before...embarassing.

Having 12V at the coil may fool you if the points are open and the circuit is open. What is the voltage when the points are closed? What happens when the points are open and you momentarily short across them with a screwdriver?

This will not apply on your 77-earlier points dissy.

FTFY.

Thanks - I guess Pertronix would be the way to go, then ?
