Hi guys, I'm about to buy a 2017 BB 500 welding machine. It has a 38hp Kubota diesel motor and it has slightly over 3k hours. The top and front skin is jacked up and the company is willing to sell it for a very reasonable price. It runs great and is possibly even quite than the MEP-803. It has a...

Hi guys, I have a MEP-803A that runs great. I'm having an issue with low voltage output. The voltage knob adjust the voltage fine until the last probably 1/3 of adjustment range, the knob continues to dial up like it should but the voltage isn't increasing past the 200 area on the gauge. This is...

Hi all! I got the 803a delivered and all my new hoses and filters in and installed. I ran the switch in the normal run prime position for a couple minutes and then cranked the motor; fired right up. This one has a noticeable vibration that my other 2 803's don't have. This one vibrates pretty...

Hi, I just bought another 803 to have as a backup. This one has "IP" painted on it. Does anyone know why they paint letters on them and what it would mean by any chance? Also, the diesel fuel hose coming off the fuel rail has a leak. Is that 1/4" hose? And should I dremel off the outer metal...

Hi everyone. Everything is pretty much good on my 803 at this point. Although the batteries I have in it are really old, the other day I went to crank it and they were dead. I charged them and ran it a couple times just fine and this morning it was dead again. I think its just the batteries. I...

Apparently I'm loosing coolant from the drain hose while the generator is running. I'm pretty sure the low point radiator pet cock is not leaking by. What would cause coolant to flow out of the hose while running? Also, the over flow tank, the coolant level sometimes rises and falls while the...

I notice I'm getting a drip of fuel running down my metal canister of the fuel filter housing. I changed the filter along with all new o-rings along with the large one which appears to be the one leaking. I removed the filter and oring, inspected it, and replaced it along with rubbing a little...

Hi all. I finally got my cannon plug pin issue resolved with new plugs/pins and ol' girl runs great, so thanks for everyone's support. Now, with it running I notice the Hz adjustment know spins and works as it should if I'm tightening or increasing the Hz. However, when I turn the knob to the...

Hi, I just bought a 803A for my parents as mine has proven to be the ticket for my needs. The one i just bought is a 2007 model, just got it home and did a filter and fluid fill, put in hot batteries and absolutely no power at the panel, no response from the fuel pumps, no panel lights, no...

I removed the top cover for the motor compartment to change the fuel return lines and notice these white cables with corroded looking wires/fittings. Are these grounding and bonding connections? I'm assuming I should make up new cables for it and replace them while the cover is off. Anyone have...

Hi, I have a fuel leak on at least one line. It looks like the return line is real wet and needs replacing. There is another line that's wet as well, not sure what hose this is. It goes up to a metal cylinder maybe a solenoid. Any idea on replacement hoses?

Curious if I can crank the generator and just let it run for several hours here and there just to exercise it without any load or if I need to at least plug in a fan or something into the 110 plug for somewhere to send some power to.

Next week I'm getting a 200 amp manual transfer switch wired into my house with a 50 amp plug. I have a 50' 50 amp cord for my supply. We are going to make up a whip from the generator lugs to a 50 amp plug we will mount to the trailer fender. What wires go into which lugs on the generator for...

Another observation I have on my new to me 803 is after start up during the warm up period especially if I adjust the hertz rotary dial the voltage meter bounces around quite sporadically. So if I have the volts dialed in at 220V the gauge may bounce around from 220 to below 150 or 100 and...

Hi everyone and happy new year. I bought a 803 with no fluids and filters. I removed the radiator bottom drain valve and flushed the radiator blowing out some residual dirty coolant. I notice the drain valve doesn't have an o-ring or a gasket of any type on it to create a seal. I reinstalled it...

I just bought a 02' Mep-803a and I'm in the process of getting it ready to start. I'm missing the wing nut which secures the air filter inside the housing. Does anyone by chance know the replacement part number or what thread size the stud is?
