Ok,

plug the red lead into the into the right pug and the black lead into the left. Set the scale at 50 on DCV. Place the red lead on the positive post of the battery and the black on the negative. Record the reading. Then with the leads still on the battery, have a helper turn the key to start. Doe the reading stay close to what it was or fall way off?

Reads about 32 drops to about 30 when starting
Expert:  Charles replied 1 year ago.

Ok,

Now move to the starter solenoid on the engine. Place the red meter lead on the side with the positive cable attached and the black meter lead on the engine block. Try to start again. If the readings are still the same, move to the other side of the solenoid with the positive meter lead and test there.

Hello Charles, back from brunch, so have cables standing by
Expert:  Charles replied 1 year ago.

Ok, hook them to the battery, then the red one to the positive post on the starter solenoid. The black one to the engine block, try to turn the engine over, it should be much faster now.

Still slow turning.... Nuts
Expert:  Charles replied 1 year ago.

Take the positive jumper cable and tough it right to the positive post on the starter. This will create a few sparks, you are just looking to se it the starter will spin faster.

Expert:  Charles replied 1 year ago.

Is the ground connection good? The motor is good, should be spinning fast.

Customer: replied 1 year ago.
Removed all grounds I think cleaned and tightened. Come on Charles , you can solve this
Expert:  Charles replied 1 year ago.

Can you take the multimeter, disconnect the wire from the solenoid, going to the starter. Then test the voltage on it with the key held in the start position?
