points, but no spark

Dear abby:
I have a '69 chevy pickup with a 350 and a points distributor. one day, i tried to start it after it had been sitting for 10 years. It wouldn't start as it had no spark. In a long series of trips to NAPA, I replaced the coil, the points (and condenser), the resistor between the coil and the distributor, replaced the switched power wire from the firewall to the starter (which also goes to the coil), and rotor. No spark. I tried 4 different coils. There is power at the points, the points spark, power at the coil, but still no spark. The only wire i haven't replaced is the wire from the coil to the distributor, but the test light lights up on it, and I forgot how to check continuity on my multi-meter (i'm electrically dumb).  Also, when I hold the test light on the points, the light goes on and off while cranking like its supposed to. Help. I even made sure the key was turned on ( i have one of those trigger deals hooked to the starter so i can crank it over from under the hood). dumping more gas in the carburetor didn't fix the spark problem. nor did slamming the drivers door, nor swearing really loud at the sky. Hamms didn't even help. The old mechanic I bought the truck from couldn't even get it to work. He suggested a mallory unilite or an HEI. To hell with that. I want points. Any ideas?

Dear Mr Johnson:
Since you have me LMAO I would really like to help you. Try the wire from the dist to the coil. I know said it checked OK, but that's with low voltage. Also I'm not sure from your description, is the rotor turning. Leave the cap off and spin the motor to see if that is working.

Love,
Abby

HEI will fix it and for cheap..... but I know want to be ol' skool......Just like the late 60's bro.

If you have power at the points and the points triger you will have spark at the coil wire....if you do not you need a new coil....I don't want to talk about coils.
