you have #1 & 2 terminals drawn wrong in your picture. #1 should be connected to exciter circuit and only have power when ignition is on. #2 should have battery positive all the time. it can be looped to battery positive stud on back of alternator but would be better connected to the fuse block wire as intended by manufacturer. then you put heavier 10 gauge wire from positive stud on back of alternator to battery positive on solenoid.
