    service sticker on 803a

    They are not all out of Albany. I've bought several with the same tag, out of OKC and Ohio. I've dealt with several and all seem to have new create motors with no other work done to them.

    MEP-003 malfunction

    I would use a screwdriver and jump the starter to see if it actually works because it grounded directly to the ground stud. If it does engage with the screwdriver, then look at the crank solenoid inside the control cubicle.

    MEP-003 malfunction

    I had a unit do this one time and it was the ground stud for the ground rod, that you are referring to. It was loose and arched causing the same symptoms. Unplug the fuel pumps and then go to prime and run to see if the breaker trips. I bet one of the capacitors on the fuel pump shorted. If that...

    803 Bogs Down and dies at 85% Load

    It's a spacer that goes on the bolt that holds the sump in place. If you look at your photos before you took it off, you can see it on the bolt, that it mounted right above the sump (holding it in place).

If he truly rebuilt the motor, you should have a higher oil pressure than 20-22psi. Should be around 60psi. You may...

    803 Bogs Down and dies at 85% Load

    What about the fuel pressure when the unit gets hot and shuts down? Hook a manual, oil pressure gauge to the line that leads up to the oil pressure sending unit. That way you will know for sure.

    803 Bogs Down and dies at 85% Load

    Ok, so it wasn't a total rebuild. He replaced rings, crank bearings, and head gasket. That explains why the oil is still black because he didn't get all the old oil out or didn't clean the bottom of the block real well. If the engine is able to make it to 80% and run fine, then quit after 15...

    803 Bogs Down and dies at 85% Load

    Did the guy do a total rebuild? If so the oil should still be a syrup (caramel) color. Now if he just changed the pistons and head gasket that's a different story. Also, your oil leak around the injector pumps could be coming from the tubes for the push rods. I've had that happen before.

    803 Bogs Down and dies at 85% Load

    Sounds to me that it the fuel supply couldn't keep up with demand. What type of fuel pump do you have? Square design or Cylinder looking design? I doubt you did any damage, the knocking was more than likely not enough fuel in the cylinder to ignite while it was shutting down. The low oil...

    803 Bogs Down and dies at 85% Load

    It's like a dimmer switch, as the lever moves to the left it slowly decreases the amount of fuel. If the rack was offset or the injector pumps were not fully engaged then you wouldn't be able to start or shut it down. Please do this before you do anything else. Take the unit when it's cold and...

    803 Bogs Down and dies at 85% Load

    Basically, there are levers on the injector pumps that fit into the fuel rail. The levers move left to right, when they are all the way to the left (towards the radiator) the injector pumps are off (no fuel), then when the rail moves the levers all the way to the right, fuel is fully open.

    803 Bogs Down and dies at 85% Load

    There are 2 holes at the top of the lever on the motor, it should be connected to the bottom hole at the top. The stop/run switch makes the injector pumps cut off the flow of fuel. For the oil leak at the fuel pumps, try tightening the nut on the hold downs to see if that helps. I still...

    002 permanent mount

    That will work perfectly, just make sure your post are in concrete and you bolt the unit to the deck. They vibrate a lot.

    MEP-803a Overvoltage Problem

    If you're getting 120 volts at the outlet, that means the generator head is good. It's either the Overvoltage relay or Voltage regulator. Voltage comes into K4 (over voltage relay) and number 4 on the voltage regulator. It senses voltage on the black wire going to the 120 outlet.

    MEP-803A backwards wiring on load gauge?

    Agreed, the gauge wires do not matter. Cleaning S8 fixes problems like this 99% of the time.

    MEP-803a Falls on its face under light load

    The cylinder reading 50 degrees lower is the problem. Swap the injectors around and see if the temperature decreases with the injector. If not, swap the pumps and then you'll know if its one of those.
