Hello, I was running my generator the other day and noticed the water temp gauge didn't move up at all. I'm wondering if that's normal or if I should start testing the gauge. I was running with 1/4 load or less and it was about 25f outside. I seem to remember it working last summer but my memory is poor. Thanks

You should check the connection on the temp sender, to make sure its not loose or broken.

The TM has excellent step-by-steps to test all the gauges. The book can help troubleshoot just about everything.

Did you notice if the fan was moving air? Check the accessory belt?

Either your gage or your sensor might be bad.
The thermostat should stay closed until the engine gets up to about 180, regardless of load or ambient temp, allowing the engine to come up to operating temp.
Only other possibility would be if the thermostat is stuck open and the engine isn't getting hot enough to register on the gage.
The TM will tell you how to test and what the ohm readings should be on the sensor, which can be tested with a multi meter.
A quick test to check the gage itself, take the wire off the sensor ( the thin sensor with the single wire ) with the main power switch in the prime/run position, momentarily touch the wire to ground and the gage needle should go up. If it does, I'd suspect a faulty sensor
If it does not move, either the gage or the gage wiring has a problem.
