no spark on my '71 Lemans Sport 350!

[Richw7]

Still no spark on my '71 Lemans Sport 350! I changed the plugs, wires, points, condenser & coil. I am getting 12 volts at the positive terminal of the coil with the key on. I followed the manual down the check list - 1) Disconnect wire at plug, check for spark 1/4" from engine - no spark. 2) Remove coil wire from distributor, check for spark 1/4" from engine - no spark. 3) connect test light from neg side of distributor to ground, turn on ignition - test light lights. 4) connect test light from point set lead connection to ground-open points (this I'm a little confused on, does this mean from the wire on the points to the base of the points set? 5) Test the coil & condenser - they are new. Any suggestions other than buy another coil & condenser? Thanks!

what voltage reading do you get at the positive side of the coil while cranking the engine to start? did you set the point gap? If you set the point gap, how did you do it?

With test light across points, when cranking engine does the light flash? It should.

The points close and charge up the coil, when the points open, the flyback effect happens and the coil lets loose with a high voltage discharge, which should coincide with the terminal on the cap.
