Got my Norton all wired up and added battery to the system but I have no spark. Got power getting to coils and points.
Any suggestions
Thanks

I assume you have checked for spark visually in some way - laying a connected spark plug on the head and, with the ignition on, watching for a spark as the kick lever or starter is operated, and you are seeing no spark at any time, right?
You mentioned points. If the ignition points don't open, there will be no spark so check point adjustment. In the old days that was one of the first "no spark" checks.
It is easy to lose/forget about/incorrectly install the little insulator used where the wire attaches to the points. Not having that insulator/installing it incorrectly will "ground" the connection and also eliminate any spark.
If you ARE getting spark at the plug sitting on the head but, when reinstalled, the engine won't fire, the ignition is likely mistimed (assuming there is fuel).

Make sure you have an engine ground and make sure your positive voltmeter lead is on the engine for testing.
The only way to have power to the points is if they are open. As you turn the engine, checking from the points to ground, most of the time you should see 0 volts and only when they open should you see about 12 volts. If they are not closing, you'll see voltage all the time.

Points open and close. Power on both sides of points wether they are closed or not.

If true, then you know the problem - the points are not electrically closing.
With properly working points, when closed they are at ground means that there will be no voltage across them.
The whole point is the make a circuit from the coil to ground. The coil will have no voltage across it (small connector to small connector) with that coil's points open and battery voltage with that coil's points closed.

Ended up being the plastic piece on the stud of the points. I had them installed incorrectly. Fixed and boom got spark. Thanks.
Thanks to all for the input as well. About to head it run tommorow for the first time in like 20 years.

Yes these forums can be as frustrating as a Commando. Like the Norton when I get wound up, just walk away and come back later.
