Back in February a non-running MEP-803a and MEP-802a came up for auction locally. I've always wanted an -803a after owning two -802a's. The -803a was missing its exhaust flapper, making me hesitant to bid on it and after asking around here, I was more hesitant. I looked carefully at the...

I'm also curious about that. In 120/240V mode, you can only measure voltage on L1-L3 (240v) and L3-N (120V), amperage is always measured on L3. That shop heater is 240V, so it has to be wired L1-L3. I have the 2 of those units and voltage makes a huge difference in how much power they pull...

A lot of baffles and sound deadening in that generator. I havent heard a 1030 or 1040 run, but the WhisperWatt generators I've seen are amazing quiet, like mid 60s dB

But how will you mix paint than?

I'm only slightly jealous. :LOL:

As a point of reference, I'm at 5280 ft and my 802a will only pull 6200-6300 watts before the engine bogs down and eventually stalls. It will stall without tripping the overload light. Can you post a video of your unit running and then getting stalled by a load? I think seeing it happen and...

Jeeepadict, I notice your location is Round Mountain, NV and some Google'ing shows your elevation somewhere between 5000 and 7000 ft ASL. NA engines lose 3% of their output per 1000 ft of elevation. Now the MEP generators have some overhead built into their design, but they do have a derating...

Sounds like you found a good one! That fuse is a modification from the original design, commonly referred to as the "quad-fuse". There is a winding in the generator head that provides medium voltage AC power to the voltage regulator. That AC power is rectified through a diode bridge in the...

Nothing critical. I was running a new-to-me 802a for the first time and watched a few embers jump out of the exhaust. I was looking for that video to show a friend what happened.

I'm looking for an old video that was likely posted here. Guy was running a wet stacked 802 or 803a (maybe) on a load bank to burn it out. I remember embers coming out of the exhaust. Thanks

Good advice. You might end up cannibalizing one for another. Or you can be a fool like me and buy one for parts, only to turn around and get it running. Welcome to the forum, this is a great group of people with a ton of knowledge.

My first thought was an ATV/SxS lift, but you would need to fabricate some crossbars to interface with the skid amd find a way to lift it onto the ATV lift...

Thanks guys! I did exercise the switches, but didn't Deoxit.

So I got another non-runner going again. I bought this one as a parts pile for my main unit, but I got the engine going and thought with some repairs, this unit could be a completed runner. It's been a struggle with missing and broken bits, but today I was able to throw a load on this unit and...

I don't recall off the top of my head what the threaded interface is on the DN2M and DN4M blocks, but the sensor is not that special. It is a fairlt standard 240-33 ohm sensor and will work with 12v or 24v gauges. So if you can find one rated for 240°F @ ~33 Ohms that fits the hole in the...

Chilbun, do you happen to own an oscilliscope?

Also rotate the engine by hand and look at the flywheel through the vent holes in the generator head. People have a tendency to jam a screw driver in there when loosening or tightening the crank pulley and could have damaged the flywheel, throwing off its balance.

I'll 2nd that. I bought a MEP-802a with a stuck pressure relief. The oil pressure was spiking to 220 psi before the lifters locked out and the engine died. Surprised the oil filter survived.

Any update on this? I'm having a similar problem with one of the 802's

You have the quad-fuse already, but plan to add the MOV to the voltage regulator.
