If it charged at all, then polarizing is not the issue.
My guess would be a bad connection or broken wire somewhere, which might be
inside the generator or control box. Grease or oil on
the VR contacts can also cause a problem.
As a side note, I discovered last year that the original control boxes rely on
the contact between a brass sleeve and the center
bolt through the relay to ground the voltage coil (on both relays). Just a
little bit of dissimilar metal corrosion can interrupt
the connection. My original box exhibited symptoms somewhat similar to those
you describe; and checking my collection of 'bad'
control boxes, I found a couple more with the same problem. Disassembling and
cleaning, followed by the adjustment procedure of
course, seems to have fixed my problem. Hasn't happened since.
There's a Lucas document at

Which gives a fairly simple troubleshooting procedure. Of course, it only
helps if the problem is happening when you do the tests.
However, since you are looking for a "no charge" condition; I might fold the
first few tests together (since it's hard to get at the
wires on the generator) and start with test 4 of Part 1. If you get the "pass"
result there, you can go on to the tests in Part 2.
The "dry card" mentioned in Part 2 can be as simple as a piece of computer
paper, torn into a 'C' shape so it will stay in the
contacts by itself.
