I rebuilt an AS2518 power supply for somebody but the game is an hour away from me, I'd like to be able to test the test points before I drive there & install it. Just wondering if there is a safe bench test that I can do.

Do you have the transformer with it too, or just the board?

If you have the transformer you can just stick 120V into the correct pins and check the test points, otherwise I don't think you can do much without a variac

Yes I have the transformer attached.

OK so I have a power cable here with the green white & black exposed. I'm guessing I can just hook up black to the A.C. Power pin, green to Power Line Ground pin, but I'm not sure if I should hook the neutral (white) up to anything. A.C. Return?

Sorry, forgot about this sitting in another tab

Should be able to hook the 120V wires up to J2 pins 6+7, and neutral to the base/ground braid

It's the other way around. 120V wires (Black and White) to J2 pins. Green to the base/ground braid.

...Isn't that the same thing? Wire colors could be anything, but the two that have 120V across them go on J2, and the third one goes to the base (or just leave it off...)

No, it's not the same. Black and white are the current-carrying power wires with black being the supply and white being the return. Green is the safety ground and it MAY be connected to the white back at the breaker panel. If you are on an isolated ground system it will not. In any event, the ground is NOT intended to be a current carrying conductor. It is solely there for a safety connection.

Don't like going by colors as I've seen them different but hopefully the OP can figure out which ones are the main two prongs...

I got that sorted out, nothing seems to test right on the transformer. Bummer. Gotta find one.
