Yep. By code you have to run the appropriate wire size per the over-current protection device on the branch circuit. If you are protected at 50a then you have to run wire rated for 50a. Using the RV panel as a distribution panel is a workable idea. Make sure the neutral and ground are not...

"Rental" engineer. Doing an expansion in Hillsboro OR for a sterile products filling plant (biopharma).

No response. I'll keep looking around though. I won't be able to do any serious work on one if it falls into my lap till I'm back at home full time at the end of the year.

Let us know how it's going.

Cool. Did it run any better? Any less smoke? Once you you know it's running well on the mechanical governor we can dive into the electronic one.

How much load did you put on it? 3kw?

If you plug your meter into an outlet in the house and get 60hz its not likely its off by too much at 350hz. My flukes are very accurate across the scale. Why that engine didn't blow-the-heck-up I don't know. It goes to show the durability of those things. Get the mechanical governor tweaked...

You are correct that the electronic governor needs to be setup. We need to get the mechanical limits of the governor set first to prevent the electronic governor from being able to push the RPM out of spec and risking damage the engine.

Yep. The bolt if I remember correctly sets the "preload" tension on the governor arm. I don't think it limits the travel of the knob. I'm afraid I'm not near one to go look at right now. BUT.. Either way you need to adjust the bolt to allow for a maximum of 312hz on the mechanical governor.

Those RPMs are a good bit higher than spec. Full wide open with zero load should be about 312 hz on the mechanical governor (3750RPM). Full load RPM should be 288 hz (~3500RPM). Someone has been tinkering with your mechanical governor adjustment. Thats why the safety wire is on the bolt. So...

Thats true if you are taking the frequency of the power BUT if you look in the TM you'll see the procedure for setting up the governor and it shows you how to take the frequency of the PMA which is mechanically tied to the engine.

Hz will be the most accurate.

That should do it!

Awesome. Let's see what the numbers are from that.

OK, that is something to measure with a current meter. The internal power meters are set for a power factor of 0.8. That means with a pure resistive load they will indicate 80% of the true load. If you run it up to 100% on the meter with a purely resistive load you are actually running it at...

How are you determining your load? Are you going by the meter on the unit or are you using an external volt/amp meter to calculate it?

Thats where I was headed next. I would recommend pining the actuator in the full open position. Check your RPM under full load. Make sure you are spinning it fast enough to generate enough power. Its hard to tell by the sound in the videos if the engine speed is right.

What RPM are you running? Does the variable speed governor work?

I think you should. Since it will pull a full load I would see how it handles it for a while.

Hm. That is a little more smoke than I would expect. Not a lot more but a little more. Hm...
