Default Re: starter voltage

Final update,
This past weekend (Jan 28-29) construction slowed down allowing me to
work on the starter (slow crank) without being interrupted.
Once I got to the starter I did some voltage measurements. Starter ground
circuit - voltage 0.23 volts normal reading 0.2 to 0.6 v0lts. Next circuit
starter power circuit - 0.05 volts normal reading 0.2 to 0.6 volts.
when I tried the next reading sparks came out of the starter. So in my
mind (drag racer) Oops their is my problem the starter was going bad very
slowly. Local auto parts store (O'Reilly's) was able to get a NOS Delco
starter.
Installed starter put everything back together . now cranks like it should
the voltage at the starter solenoid now reads 9.9 volts while cranking with
Battery voltage reading showed 12.7 volts before cranking.
thanks for the help that made me think.
