What would the risk be if he jumpers out (or opens) the MPU output contact to verify if it is the MPU or not?

Now if someone could find some hoses for the 802A, that would be great!

Has anyone ever had their MEP-531A wet stack? I was always under the impression that those run so hot that anything in the tailpipe would just burn out. At least that's how mine stay clean. I was just on the Dewey Electronics website, and on their generator accsessories page they are...

A current sensor is basically a current transformer that transforms current to current at a specific ratio. I don't know what the ratio on the generator CT is, but the industry standars is current input / 5 amps output. so a 100/5 transformer would give you 5 amps out when the wire through the...

I get most of my fasteners (stainless and otherwise) from https://www.albanycountyfasteners.com/ .

Need to make sure it was hot! A bad head gasket ( or worse) can blow coolant all over the place also. The reason I mention that is, you stated you got a lot of black liquid out of the radiator. Usually it is antifreeze color or rust color for really old antifreeze, not black. The crunchy hoses...

Most equipment can actually be operated on both frequencies, if you can live with the necessary derating factors. Back when I used to do real work, I frequently had to deal with different frequency equipment as well as variable frequency equipment. It was interesting while working in different...

How many hours do you run the machines between filter changes, and between oil changes? Sounds like you have some very reliable engines.

That is the flowrate that the pump will put out if open ended into a bucket. When it's dead headed into an injection pump, the flow is reduced, and the pressure maxes out at 7 psi.

Keep looking on GovPlanet. They just sold three in the last two month. Don't know if they worked, but it would be a start. Search for TRC 29350. I have also seen them on E-pay.

I would recommend a section of flex metal hose at the machine ( McMaster Carr, search for " https://www.mcmaster.com/5262K59/ " for an example). As much as these machines vibrate, any hard pipe connected to the exhaust manifold will create major stresses in the manifold. I used the galvanized...

Rock Auto has them on their website for $7.72. https://www.rockauto.com/en/parts/airtex,G17,,0

Just a WAG here, based on the symptoms. On the first start, the oil is thick and builds up enough pressure to run the engine at 18oo rpm. When it's hot, the oil viscosity is too low, and at cranking speed, cannot build up enough pressure to get the engine to run, and trips on low oil presure. I...

Biobor and PRI-D. Shop around for the lowest prices. I was in a hurry and went to a West Marine $$$. I also recommend somehow circulating your fuel to get the biobor and PRI-D mixed in well. Biocides don't remove any sludge / contaminants; they only kill anything and everything that grows in the...

There are two boxes listed on epay right now, one for less than $300. Search for MEP-903.

I am considering buying a 24" light bar. Does anyone know if the HID light elevation can be adjusted within the box, or do you have to move the whole box to adjust the lights?

On an aside, did you see any smoke coming from behind any panels, or from the generator itself while running, or only from the engine exhaust? This is a lot of current going somewhere, and something is severely overheating with this much power. Also, don't run the generator. In case it is a...

The 133% is telling me that the generator is producing power when it's running, but it's going somewhere else. I would definitely pull the top off the machine, and inspect the wires between the generator the voltage selector switch (the big switch behind the back panel), and contactor. Look at...

This sounds suspicious. Did the meter read 130% with the output contactor open or closed? The current transformer that measures this is located in the generator output wiring. This would indicate that the generator was producing power, but feeding an overload or short circuit. I would pull the...
