The car does not crank only thing I hear now is a metallic clatter sounds like it may be coming from the starter but before I took off the pos it only sounded like a low battery and would start if I charged it

If the starter is inop I would make sure the battery cables are clean and tight. Also make sure the battery tests good and is fully charged.

The battery tests good, I was wondering if there is a way to see if the computer is working without a tester obd2 it seemed to be an alternator problem(as it sounded funny) I think I damaged something as the problem seems totally different now
