This forum was helpful in troubleshooting my problem, so I wanted to
contribute my findings.

I've had a Grizzly G1023S for about 6 years. It's a fantastic saw,
but it stopped running yesterday. I pressed the start button, and for
a fraction of a second it got juice, then nothing. I wasn't able to
get anything after that point.

Here is the troubleshooting process I should have used:
- Use a multimeter to verify 240V at the wall. Should be approx 240V.
- Open the magnetic start switch (If you look very closely at the
bottom of the switch, the word "open" is molded into the plastic.
Push there.)

With the saw plugged into the 240V outlet:
- Use a multimeter to verify the voltage between L1 and ground.
Should be approx 120V.
*** THIS WAS MY PROBLEM ***
- Use a multimeter to verify the voltage between L3 and ground.
Should be approx 120V.

With the saw unplugged:
- Verify the resistance between the ground on the plug and ground
inside the switch (should be approx 0 Ohms)
- Verify the resistance between one power prong on the plug and L1
inside the switch (should be approx 0 Ohms)
*** THIS WAS MY PROBLEM ***
- Verify the resistance between the other power prong on the plug and
L3 inside the switch (should be approx 0 Ohms)

This confirmed my problem. I checked the length of the power cord,
and it was all intact. I knew it must be in the plug. When I opened
the end of the plug, I found the red wire was broken where it connects
to the power prong. I wired up a replacement and I'm back in
business.

I hope this helps someone else.


Burke;
Thanks for the post - it inspired me to do some troubleshooting along the lines of what you documented when my Grizzly 1023 stopped working suddenly. I have had some issues intermittently with the saw shutting off for no apparent reason and then restarting after a slight pause. No signs that the motor was fatigued so I suspected something electrical. Anyways, today it stopped and did not restart. I saw your post and started down the same path you outlined (after replacing the batteries on my volt meter of course). In the end I had a wire at the plug that had come loose. It was very obvious when I opened up the plug and saw the wire blackened and almost fully disconnected. Anyways, after stripping the wires back and rewiring the plug it worked perfectly (nice to hear the soft hum of the Grizzly again). I'm not sure if this was the factory plug or had been replaced by the previous owner since I bought it second hand but definitely something to keep an eye on.

Thanks for the inspiration and for spelling out the thought process.
