How do I check the coil points and condenser

I am still waiting on an answer.
Expert:  K. Wiggins replied 10 months ago.

Good morning, first thing I suggest doing is checking that the points are working properly. Disconnect the wire from the coil that comes from the distributor. Set you voltmeter to ohms and connect one lead to the wire you just disconnected and the other lead to ground. Now loosens the distributor and turn it until the points close. It should show continuity to ground on the meter. Now turn the distributor until the points open, there should be no continuity to ground.

Let me know what you find and we can work further if needed.

There is no wire coming from distributor. There is a power wire coming from a voltage regulator. It is supplying 6 volts to the coil. I checked the little spring in the coil that touches the points and it has 6 volts. I also check voltage to the condenser from the coil and it is 6 volts. I check the ohms on the coil and it is a little over 8 ohms at 20000k. There is no ohms on the condenser if I check it correctly. I have not checked the points for u do not know how. But I can do what your instructions say if you further explain what you mean by distrust or wire. This is a 1940 v8 flathead ford.

Boy that's sweet . ok lets do an old school test, you said you have 6v to the coil and it goes through the coil to the points right? ok I want you to open the points and using a jumper wire with an alligator clip put that onto the point side of the coil , un hook the high tension side of the coil and hold it close to a ground ,about the same distance as a spark plug with key on touch the other end of that jumper wire to ground and off as if you were the points opening and closing and see if you get the coil to spark. Tell me what you see .

Customer: replied 10 months ago.
Ok. I will do this. Question: when you say the "High tension side of the coil..." do you mean the side of the coil that touches the rotor? Also, I will going out of town today and will not be back for one week; so, it will be a few days before I can do this.
Expert:  Peter Bagley replied 10 months ago.

I mean the output to the spark plugs. talk latter.
