I'm thinking of buy a used vacuum pump.

Gast 0523 but wired for 220. A big problem is that the seller does not
have 220 to show me that it works. The location is close enough to
drive to but far enough away that I don't want to drive back.

How can I test that the pump works?

Borrow a small generator?
Anything with 220v output should work, the pump can't draw many amps..



if it works, how much should I pay for it?

owner thinks he can rig a 220 for a test
