Low Voltage from Portable Generator
During our recent hurricane here on the East Coast I had a problem with my portable generator. It has been very reliable for ten years, but this time it was working fine, then the engine cut out with a load on it. Then after restarting - the voltage slowly dropped until it was only producing almost nothing. The engine did not seem to rev under load like it used to do automatically. When I manually revved the engine the power did increase.
I don't have a voltmeter so I can't tell you the exact voltages, but it would barely spin my power drill when I used it to test the outlet. The oil and gas levels were okay. Is there some kind of sensor that tells the engine when to rev when there is an increased load? Any ideas what may be wrong?
Please don't tell me to take it in for service as this is a permanently mounted unit and there is no way I could transport it. It is a North Star 5500 watt unit. Thank you for any help!
