MEP-804B Questions

[Rik]

I purchased an MEP-804B generator and I have just a few general questions if someone can answer.

The AM/VM switch, am I incorrect in thinking that this is merely a reading of the ”L” legs and not a switch at all? Meaning it does not turn on/off anything just reads the current across the labeled legs.

Is there a circuit breaker for the generator? I see one for the 110V/10amp outlet but what about the “L” legs of power? Are these unprotected?

I have a small fuel leak, due to the freight company, that involves the fuel drain on the side of the generator. I have not been able to find a drawing of how this is installed nor attached to the generator itself. The shipping company hit it with their forks or rammed it with the pallet jack. Can this be removed? I see when the generator are mounted on a trailer that the drain is in the rear vs side.

Thanks in advance

The AM-VM switch just connects the voltmeter and load meter to the various points. It does not have anything to do with switching power to the lugs.

There isn't any "circuit breaker" for the output at the lugs. The generator has current sensors for each of the output legs. If the sensors detect and overload condition the generator will open it's contactor removing power from the lugs.

The valve simply unscrews from the elbow. A common part number for the valve are Parker-Hannifin NV108P & NV108P-4.
There are a zillion others that fit too.

I suggest you download the Technical Manuals for your set from the TM section of the forum. There is a wealth of information in them.

Thanks. The valve is not leaking, rather the point where the assembly enters into the side of the generator (tank?)

Check the -24P TM. It has a diagram with all the parts that make up the drain with part numbers.

Anyone know what brand or weight of oil these generators require?

TM says 6 quarts of oil but nothing about the grade or viscosity requirements

please read all of the TM's they give you all of these common questions.

The info is in the -24 TM. You need to dig a bit deeper. Look for the LO, Lubrication Order.
