squareback alternator wiring in pre 70 car issue

I used a multimeter and an aftermarket guage at the battery terminals and both read the same. I had the battery tested and they said it checks out and no dead cells. I ran a jumper terminal from the 2nd FLD to the blue wire on the old style/solid state VR and it is still in the 12's (per a few members). I took the bulk head wiring plugs off and inspected them and they are clean. All I have to do to switch it back is pull the blue wire I ran. I will get some more readings tomorrow
I'll keep you posted.
