help! chargeing problem since mad bypass!!

Ok, I did the " mad " bypass a month or so a ago on my sons 74 Duster, I was diligent to follow the instructions with proper solder and splice connections as directed when I was done I started the car and it ran fine however I didn't check the charging system output, I know it was ok before I started because the car was driven daily last summer, so we are getting ready to take it to the exhaust shop tomorrow am as it has open headers now and I discover this problem, here is what I have done to diagnose.., checked charging system with volt and ammeter, the battery which was new last year and just came off the battery charger last the other day, I have 12.2 volts static and while running, the alternator output at the + post is the same I have three spare alternators and to the best of my knowledge are all functioning properly, I swapped with all three tonight, same results, I pinned the wires at each end of the bypass ie: from the alternator + post to the fusible link at the starter relay and had continuity, ie: no blown link, as a hail Mary I even had a spare good voltage regulator and tried that as well but same results, I was reading through my service manual trouble shoot guide and it suggest high resistance in the fuse-able link, the only place I strayed a bit from the " Mad" bypass instructions was using 14" gauge fuse-able links going to and from the starter relay, could this be my problem?, what have I missed?, any help here would be good as I have an appointment at the exhaust shop at 9:00 am tomorrow and I am about 8 miles from the shop too far to drive with no chargeing system.
