Re: No spark to coil

I am not familiar enough with that dist to know for sure where it gets a solid ground from since it rotates. Cortcomp says thru the clamps and there is an extra ground wire showing in the parts manual from the vacuum advance setup to the distributor case.

I think you said you had spark from the coil to the dist but if not, Remove the high voltage center conductor from distributor and place end near the block -- about 1/8" or so away. Then remove the green wire from the distributor primary coil terminal and with ign key on, touch it against the block. You should see a small spark and when removing primary wire from the block, the coil should generate it's big spark. If it does, problem lies within the distributor or points. If no spark, problem is with the coil. You may not see much of a spark at the points because that is what the condenser is supposed to control.

If you get a spark, reconnect the primary green wire to dist and crank the engine leaving the center coil wire near block. You should see many sparks. If not, a distributor or points problem. I don't remember the exact unit but there have been reports of some replacement rotors not quite lining up properly because the notch was different or not being high enough to reach the cap. If you changed the cap or rotor did you verify the replacements are identical with the old.
