Like Old sez, positive ground, plus to points. (tip # 33 at the link below) But, even if you had it backwards, it shouldn't result in a 'no spark' condition. Is it a front or side distributor?

The fact that it sparks doesn't tell you how much voltage you have. You really need a meter.

Verify the gap on the points at .025. Then, run a new clean dollar bill through them. New points sometimes have a residue & old points can corrode, or get grease from the distributor cam on them. Or, you could have used a dirty feeler gauge. (I always spray mine off w/ contact cleaner.) Make sure you have voltage across the points, as in past the insulator on the side of the distributor. That insulator is the number 1 failure point on a sidemount. If you just replaced the rotor & lost spark, put the old one back in. Check continuity on the secondary coil wire. Make sure it is firmly seated in both the cap & the coil. In fact, replace it temporarily w/ a plug wire. Post back w/ results; I'll be interested in what the problem was.

What ever your ground is is also the side of the coil that goes to the distributor. So if + ground the + side of the coil goes to the distributor
