Battery draining fast

I've ran a new green wire from the single field round back alternator .
I've tested the big black wire from the alternator to the bulk head connector pin for continuity .
Tested the black wire going thru the amp meter coming out red back to the bulk head connector FOR continuity .
The blue wire has 12 volts to ground .
The green wire tested 2.4 volts
Traced the red wire which is connected to the battery cable at the starter .
Ran a black #14 wire stranded to regulator looped over to alternator housing straight to the battery's negative pig tail .
Removed rust from the fuse holders with navel gel and steel wool q- tip
Cleaned every connection in the engine compartment
Took bulkhead connectors off and filed the blades and cleaned the female contacts
Replaced alternator
Replaced fusible link
Repaired crappy splices
Pulled out the radio the previous owner installed with twisted wires and black tape .
