Keep getting under voltage fault. I have cleared fault several time. generator will run for short period then fail.sometimes the fault is underspeed.


See if reducing the number of things connected to the generator will stop your problem. Disconnect or turn off some things that are not totally necessary.
To properly generate electricity, the engine is required to maintain an rpm within a specific range. If you load down the generator with too many things pulling power, the engine will not have enough HP to turn the generator within the set rpm range. It goes under-speed or under-voltage and you get a fault.
Going to the extreme, if you disconnect everything from the generator and it still fails, you have a generator problem

Generator alarm underspeed


When you get the under speed alarm is the generator under load? Try manually starting the generator with no load and let it run for a while, if no alarm, then put it under your home load and measure current draw (maybe have an electrician check it) if the amp draw and in rush caused by compressors, pumps motors etc are within the generator rating, check your fuel pressure, on average 8-11 WC Nat gas. Pressure may test well under no load but drop starving the engine of fuel unde rload. Underspeed is just that engine cannot make RPM/Frequency

My coleman powermate 1850 will run for about 15 to 30 min, then it shuts down. Then I have to wait 1 to 2 hours to start again. could it be the low oil switch has gone bad? or is it a plugged exhaust


Could be a bad magneto coil, check for spark right after it shuts down. If no spark you need a new coil, If you have a bad coil it will heat up and will not generate a spark but after it cools down it will work until it gets hot.
