MEP-003 recovery and adventure

What happens under load?

The only thing I have handy to load it up with is my house. I really don’t want to smoke all my electronics testing it. I thought i would ask some options before I plugged it in.

Plan B is to kill everything but the dryer at the breaker and see what happens.

Did you happen to see what his bouncing meter read plugged into your house line voltage? That would be a way to test both his meter and your kill-a-watt.

The volt meter read exactly the same weather it was plugged into the convince receptacle or directly on the output lugs. It was just easier to show the meters in one frame the way I did it.

The volt meter also read the same on the output of the 50 amp box that will Be the output to the house.

I plugged my cheap-o meter into the exact same places as the electricians meter and it always read within a 10th of what the kill a watt meter was reading.

Sorry, I was meaning did you use his meter on your house power to see if it was steady or fluctuating like on the Generator. That would give you confirmation that his meter is acting up or the generator output could be.

Normally for the frequency to be all over the place the engine RPM would have to be wildly changing. I assume it's steady.
The output waveform from the generator may be distorted and causing the electricians meter reading to jump around.
I'd suggest using an oscilloscope and looking at the actual output waveform to see if it's a reasonable sinewave or not and if the frequency is 60 Hz.

If the kilowatt meter is digital, it will not show "real" frequently. It shows an average reading. To see properly, what is going on with the frequency, use an analog meter for quickly measurements and an O-scope, like Kloppk susgested. The O-scope is of course the best method.

There are several different types of frequency irregularities. One is called a "hunt", or surge. Rarely seen in the small generators. It comes about normally due to a non functional electrical governor actuator system. It's normally a short surge, the gov system corrects, Clowers the engine speed) then the governor sciences low speed and over corrects. And on and on and on and on. If left un attended, it can hunt 100 times a minute, or more. Or it can be a very slow hunt. In any case, bad for the end user. Then come the slow decrease, ( very seldom but can happen, an increase) of frequently. This is 99.99999999% a fuel problem. The slow increasing problem, is also a fuel problem. But as I said, rare. One last problem. An over speed/max frequently problem. I have only seen it a few times. Always an injector pump problem. Mechanical problem every time.

if you know someone with an O-scope, try that first, before jumping to conclusions. Your Electricions meter may not be right. But first check it with the O-scope. If the O-scope shows dirty frequency, then we can think about what might be the problem. We might think about calling Dieseladdict in, he is an EE. Electrical Engineer, I believe.

I am currently on the hunt for an O-scope. I will give an update when I dig one up.

Just a follow up note on this one.

I had an issue that was generated by a bone head move. You can read all about that here.

Since then I have gotten it back running and tested. Everything is working as it should.

As of now the house is being powered by the 003 as some dummy hit the light pole on our road and knocked out power. Thankful we are still cool as a cucumber and I am washing clothes.

judging by the keystrokes on your post. may i assume that someone has finally bought you a beer? wink

Typo's what typos's? It was clear as a Weihenstephaner Hefeweissbier on a Friday night . However, the posting date of that particular reply would suggest that it was New Years Eve 2017 and he might have been getting a head start enjoying some of his home fermented hooch or there were some translation errors induced from his deutsche based keyboard.

See guys!! A true friend!! Got my back. And you have no idea how many problems come from these dang keyboards. The whole household wants German. I want US. The desktop has German. The laptop has US. The tablet has German. Sometimes I look up at the screen, and think, I haven't had THAT much to drink. Its Wednesday night, just came back from the Buffalo House, and had a Jim Dandy burger and rings, with a half ton of sauerkraut on the burger. A two fisted meal. Now I can drink a beer to go along with it. Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!
