spark and no spark

Very interesting results.
With the meter clamped to the large bolt on the starter, the same one that holds the + cable from battery, with the grounded going to the motor. 12.2 volt initially and 8.37 volts when cranking.
So from there I went from the motor being the ground to a place on the frame I cleaned off as ground. The meter now is 8.57volts initially and 5.7volts when cranking. This is with the meter still being clamped to large + starter bolt.
