Okay, first of all this document is written for a negative ground car and you have positive ground, so to use it you have to change some things. Like it says touch the + lead to arm and – to ground. You should do the opposite, etc.

Also you say the generator is a B type but per the test I asked earlier the results indicate an A type. An A type is also correct for your car.

To confirm, we can check:
- when the – of your voltmeter is on the arm terminal, and + on ground, with the car on, you should see some positive voltage. If it's negative, your generator is polarized backwards. (If you have an analog or cheap voltmeter that cannot indicate negative voltage, switch the leads to check for negative voltage.)

- perform the same test but with the field terminal instead of arm.

You should disconnect arm and field from the regulator during these tests.

If on the second test you get armature voltage between the field and ground, you have a Type A generator. If you get no voltage, you have a Type B generator. This is a internally hardwired property of the generator, unaffected by polarization.

Edit: saw your edit.
