First I'd check your drainage setup, is it clogged? That would cause condensation to form

Primary drain line clogged causing secondary drain to flow? May want to simply clean drain pan with warm water and a paint brush. no chlorine. It’s corrosive. Vacuum out condensate line with shop vac.

BTW, suction line wasn’t ran in a friendly way. Makes it harder to service.

The little drain pain (inside the unit) is the primary pan. That should be the only pan that collects condensation. The big outer pan (under the whole unit) should NOT be catching water. It is a back up pan. I assume that this unit is in the attic, which is why you have a back up pan (to prevent condensation from leaking on your ceiling). It looks like the main drain is clogged. Which is why water is draining out of the secondary drain.

Not an expert at ac repair but I have had the pleasure of replacing a few coils from pinhole leaks caused by the rusting steal cab around the copper coil. On the happy side the new coils now have plastic around the copper to prevent this issue.
