charging issues on genIII swap

as mentioned, everything in the car from the fuse box is stock. the fuse box gets power straight from the battery cable(0/1 gauge) from the ford solenoid post . the hot wire from the alternator(4gauge) goes to the same hot solenoid post. the yellow wire from the factory solenoid powers the ford solenoid when the key is turned , a 0/1 gauge wire goes from the dead side of the solenoid to the starter. the 2 starter posts are tied together. this is a hemi swap...everything is new, the engine and everything else is grounded straight to the battery, no chassis grounds are used . new ground straps everywhere..
