Sorry I left for awhile, believe it or not there is life outside the internet....
I think he wants u to test those wires from the dist while you crank it over and then ck millvolts while cranking
Correct, The leads from the distributor not the leads that go to the ignition module...
The pickup coil (stator) pictured about creates the low voltage signal that triggers the module... The module turns that into the ground side pulse that causes the coil to fire the high voltage spark....
If your concerned about the voltage temporarily jump 12v from the battery to the + side of the coil..
BTW I grabbed the schematic off the net, I didn't notice the extra balls & Holley projection add-on... Ignore the extra stuff & the schematic shows the circuit..
