It makes no noise at all, I've tried to make it spin and their is nothing. Does not smell burnt, the inside where all the wires etc are in, was not dirty.Lee; Does the motor make a low pitched hum when turned on? PS, Don't leave the switch on. unless you are working on it. The motor will overheat if power is applied and the motor isn't spinning.
The power switch on lathes is NOT sealed, so dust gets into the switch and prevents it from making contact. Blow out the switch with compressed air.
The spin the spindle is a good test. Many motors have a "start" / "run" switch in the motor. the switch is normally closed when not running and cuts the start capacitor into the circuit. When the motor starts spinning the switch opens and the capacitor is taken out of the circuit.
I will say this a motor will not just stop working. If you do not smell burning than that motor did not burn up. I would look at speed controller or wiring inside. Speed controllers are known to fail. I assume you tried starting while going through the speed ranges with the knob. I am still leaning toward vibration being a cause. What were you doing when it stopped running exactly. ?Nothing happened, new fuse, new brushes.. So frustrating!!!!
I was turning a pen at 1400 -1500 RPMs and all of a sudden it just stopped. The tech guy from Grizzly told me to make sure all the wires inside are well connected and if they are to check if power is coming to the machine and out to the motor. I need to get a meter deal to do that.I will say this a motor will not just stop working. If you do not smell burning than that motor did not burn up.

How would I know if the circuit breaker tripped? Is their a reset button somewhere that I'm not seeing?I was looking at a schematic for a SHOP FOX W1704 online and it looks like there is an external fuse which I assume is the one that you referred to. It also shows a remotely mounted circuit breaker that is wired into the control board.
I suppose the paddle switch could fail, not very likely though.
If the Fuse is good and the circuit breaker is not tripped, and the motor didn't smoke or anything, it is probably a component on the control board itself.

How old is this lathe? The instruction book posted on the Grizzly site do not show a circuit breaker in any of the pictures, and there is no reference a circuit breaker on the electrical diagram, but it is clearly marked as applying to machines made after 1/20. Dave posted a circuit diagram that shows a circuit breaker, and I also found an earlier (2013) version of the instructions on line that does show a breaker in the circuit diagram. The current instructions do mention a 'machine circuit breaker' as something to be checked if it isn't working properly. But none of the pictures show a reset button, and Lee reports that he can't find one,. None of the parts lists I've seen mention a circuit breaker as a stand-alone replaceable part, but it could be something incorporated onto the circuit board.How would I know if the circuit breaker tripped? Is their a reset button somewhere that I'm not seeing?
Thanks
I seen that add also, I reached out the seller. Very much appreciated for your help.Have to say I did a google search for the instruction manual for this lathe and have to tell you just about every link I open had a virus or a security breach in it. I will pass on giving any more info on this lathe. Good luck. This in my opinion looks like a very low end lathe to begin with so it maybe just worth moving on a step up to a better lathe before spending too much money on it.
Saw this on ebay. Maybe a good thing to try

No he was referring to a so called circuit breaker within that circuit board diagram that was shown. If you look it says circuit breaker. Not sure what that would be especially when there is a power fuse already.I suspect he's referring to the circuit breaker at your house - there should be a panel somewhere with a bunch of, well, circuit breakers in them.
Likely looks something like this Check for any switches that are a little offset.
If you can't find it or it doesn't look like there's one tripped, a AC ground outlet tester is a cheap$5$10 tool to check the outlet itself
