- static positive coil - 12.85v
- static neg coil - 12.85v
- crank battery - 11v
- crank neg coil - 7.42v

test:
- coil wire spark - there but weak
- in line plug spark checker - there but weak
- direct connect battery to positive coil - 12v static; 11 volt crank and nostart

Dist sent to MSD for rebuild.

More to follow...thanx for all the help.
That NEG coil voltage while cranking was measured how?
That would be an RMS value of 12v to 0 volts back to 12v, duty cycle dependant, or in other words - dwell angle.
Did you measure the coil wire resistance?
What gap does the spark jump?
