No spark- what am I missing?

Here's a plan. "Gets you back to basics"

First SIMPLIFY the thing

Remove ALL wires from the coil except the distributor to coil primary wire

Use a jumper from a battery source to the coil to power for testing. Do not leave this hooked up, you can burn the points, and ruin the coil

With power hooked up, check your dwell cranking.

Bump the engine until points are closed. Power up the coil with your jumper and quickly check voltage at both sides of the coil. You should have

"same as battery" at your jumper on the coil +

and very near zero volts on the NEG terminal. If you read over 1 V those points are junk. And THAT is giving up a lot. The reading should be MUCH lower

"Assume" the coil HT lead might be bad. "Rig" a grounded wire and screwdriver probe, and while using your remote switch, hold the probe into the top of the coil, look for spark while cranking. You should get an absolute min. of nice blue 3/8" spark, and often more like 1/2" long

if you don't get a spark doing the above try....


Yet another condenser

You say? You get a "good" spark while manually shorting the points with a screwdriver? This might hint that even though you think so, the points are not really closing. I'd pull them out, inspect, and inspect the distributor for wear / shaft bearing wear. Or maybe you don't have them gapped as you think.

(Maybe the dwell meter is bonkers or you have it set wrong. Make sure you are reading the correct meter scale and have it set for 6 cylinders)

Is the distributor actually turning with the starter?
