Year 1992

Battery drains when the car is running. Alternator isnt holding charge?
Took the alternator to get checked, passed 3 times. (Auto Zone)
Took the battery to get checked passed. (Yellow Top)
Bought New Belt, old one was worn.
This Picture shows parasitic draw? i pulled and checked all the fuses but it still reads 10.8

No aftermarket radio
Checked all my grounds, Cleaned them and all.
runs for 5 - 10 mins then dies.
When i charge the battery to 12.6v i can start the car. but after 5 - 10 mins the car will shut off. either the alternator isnt holding the charge or the battery has a bad cell. but i got both of them checked at auto zone and passed
So this lead me to check for a parasitic draw, so when i ran my multi meter on the negative terminal i came up with 10.85

All it shows is that you have a bad connection IF you have had the battery load tested and the alternator load tested, not just tested for voltage while without load.
Bottom line however is simple......... no car will cut off with a working alternator. The battery is irrelevant once running. You can take it out, put it in the seat beside you, and put a little hat on it.

Nothing about that indicates parasitic draw or anything related to it, nor does your reading have anything to do with a draw in any way. Parasitic draw is amperage, not voltage. Not even in the same ballpark.
All it shows is that you have a bad connection IF you have had the battery load tested and the alternator load tested, not just tested for voltage while without load.

So it has to be the alternator. Gonna replace that and be golden again.
