Still no spark on my 50

I went back to points since I had no luck with the Pretronix and installed new points condensor and 12 volt coil with internal resister. (no ballast resister) Still can't get a spark. I have 12vots at the positive terminal of coil with ignition switch on. I attached a test lamp to the wire coming from the negative coil terminal to the distributor. With points cl;osed I have the light on. When points open , I the light stays on , From what I read, if the test lamp attacked to the lead to the distributor never goes out, then there is a problem . Since the points are new, the only thing I can think of is the distributor is not grounded. How do you check this?

The light staying on with the points closed indicates a lack of ground through the points.

Did you clean the contacts of the points with some card stock, brown paper bag, even a dollar bill?

Inspect the lead wire from the coil terminal to the distributor and inside the distributor where the points and condenser leads connect together to be sure they are clean and tightened together.

With the points closed, use a jumper wire between the side of the points that is screwed down to the breaker plater and a good ground point. Does you test light on the negative terminal of the coil go out when the key is turned on, when the jumper wire is in place?
 
We had a puller G that we wanted to test run it before painting. Fired right up on the first spin and ran good so stripped it back down and painted it. Reassembled it and it would't start, Finally took the dist off and cleaned the paint out of the governor housing. It fired right up after that. We also had an A that didn't want to start either. Finally took the dist off and cleaned up the governor housing again and i fired right up.

I agree, clean the new points. Ron MN
 
As others have said, clean the housing. The test would be continuity on a multimeter (beeper setting) get bare metal one probe to distributor one to tractor governor housing. It should beep or needle move.

What I do is use the tip of a small screw driver and if I see a spark I know the points need TLC
