Ah, more information…
Do I understand correctly that you're trying to run this phase converter off of a portable generator? What's the generator rated at?
If yes, that's (most likely) not the source of your current problem, but depending on the size of your generator, could prevent things from working even if we get the phase-a-matic sorted out.
As an aside though - are you sure that you've actually applied power to the 3-phase motor on the lathe? Does the lathe have a switch, and did it get turned on? Also, does the generator have a circuit breaker, and is it still engaged? (I don't want to admit to how many hours I spent chasing what I thought was a wiring fault between my shop and house, in the middle of the night in a thunderstorm with a flashlight, when we had a power outage and I tried to back-feed the house power from the big generator in the shop -- turned out to be a wildly asymmetric load on the 220 output that tripped protection on the generator, and it took me ages to get all the way to checking the obvious).
To set your mind at ease that the 3-phase motor is still good, you can try the same pull-start trick on it that I suggested for your converter, back when I though you had a rotary converter. A 3-phase motor will run "ok" on single-phase 220 (that's all that the phase-a-matic is doing), it just can't /start/ on single-phase.
Again, unload motor (belts off). Wrap a pull cord around the shaft/pulley and give it a good yank. Apply 220V power across any 2 leads on the 3-phase motor while it's spinning. If that winding set in the motor is good, it'll spin up (or, possibly decelerate - can't remember whether that's actually possible and don't have time to draw the picture right now). If it starts running, disconnect power, swap one leg of the 220V to the remaining 3-phase lead, pull-start it again and apply power again. If it again spins up (or rapidly brakes), the remaining winding is good too.
If all that's well, we can get to diagnosing the phase-a-matic.
Alternatively, and if your setup really is generator-only 220V in the shop, I concur with the others - you'd be much better off swapping the 3-phase motor for a 110V single-phase. Southbend sold lots of lathes configured that way, so it's not a huge violation of the original spirit of the machine (and believe me, I do understand the "I like original" mindset - I'm currently building a 480V 3-phase system to parallel my existing 220V 3ph system, entirely because I don't want to rewire a recent acquisition into a configuration that was never a catalog-configuration from the manufacturer. This is doubly ridiculous on my part, as reconfiguring the machine would actually be straightforward - the motor is dual-voltage. Anyway - let's say I understand obsessive-compulsive on these things…)
If you'd like to go ahead with diagnosing the phase-a-matic, open it up and send us some pictures of the guts. I don't have a phase-a-matic schematic for reference, but they're conceptually really simple devices, and many of us here can help point you at the places to check with your multimeter, and what you should be seeing when you do.
