Need help badly with charging system

I checked the belt it only screeched under load when it was charging once it stopped there was no noise I checked the belt right away I will get some electrical cleaner and spray the bulkhead I'm just scared to drive it the way it is . And I did see I was getting 1.9x v at the fld wire on the volt reg I'm thinking of making a new field wire and bypass the original the manual says u should get no more then .55v from the fld wire
