MG MGA - battery not charging

With new regulator and a rebuild of the genarator I still have no charge into the battery. The integerity of the wireing is ok and an Auto Electrican has not been able to fix it. Joining the F and D wires produces 20 plus volts and 25 plus amps at a fast idle, so the generator is ok. There is only battery voltage at the A and A1 terminals, the ground to the regulator box is good. Any suggestions gratefully received Thanks Sean ( '57 A positive ground)
P.S. Is it possible to test the new regulator off the car ? ?

Very common is bad connections to the batteries, either cables to clamps or clamps to posts (or the combined effect).

Remove the regulator cover and watch the cut-out (the bobbin on the right) as someone starts and slightly revs the engine, does it operate? If it doesn't then you may have a faulty cut out coil or dirty regulator contacts. See what happens.
Lindsay Sampford

Has the auto-electrican checked both batteries as well

New regulators have been setting in the box for many moons.,. All you might have to do is clean the contacts.(burnish) use 4-600 grit wet or dry followed by solid cardboard to clean up the dust.
Moss even suggests that with replacement units.
