Battery draining fast

ok charging battery today removed the bulkhead connector used 300 grit sand paper glued to feeler gauge to clean all the blades .I also removed the connectors from what I now know as the starter relay and cleaned those contacts . I pulled the fusible link off thanks to all of your replies and it fell apart there was only a few strand holding it together . Im going to put everything back and see what happens then test the green terminal to output terminal if this dosent work.

Some one should make a sticky of a picture with all the relays labeled for dummies like me !
