OK

That test was to verify we have a good ground at the distributor, We want to establish that first b/c an open ground results in the same No Spark condition as a No 12v + would... need ground for Pert to complete the coils circuit.

Next test is to see if you have 12v+ at coil when key is turned to the START position...we know you have power at Run position, so now check Start position and report finding.

Note *
I am assuming you have a No Spark condition and your problem is not gas,etc. related .. have you , in fact, checked for spark at a plug or primary wire??????????
