    MEP-803A Batteries & Long Term Use

    I don't think the 2x2 would suffice. Your fuel pumps and Fuel solenoid will probably draw more than that and slowly deplete the batteries, not to mention the need to recharge the batteries from the start up draw. I'm sure someone had done a load test on the DC system and can post the typical...

    803A droop adjust screw?

    The shims don't adjust the amount of fuel being delivered, they adjust the pump timing. Rotating the pumps within the block adjusts the amount of fuel being supplied by altering the position of that slash cut notch in the plunger.

    Mep 803 alternator test?

    Also, don't rely on the accuracy of the machine's temp gage. Typically they have a 180* thermostat but the gage tends to read 20+* hotter than the machine really is.

    Mep 803 alternator test?

    Precisely why everyone should keep a "Spare" generator on hand! It is soooo... much easier to diagnose issues and swap parts to verify! Green Machine Fever at it's finest!

    Mep 803 alternator test?

    That's your problem! That is the fuse holder for the alternator, supposed to be a 30A glass tube fuse in there, your typical 1 1/4" automotive style. I bet @Light in the Dark or @kloppk have a source available for a new holder, unless you see a gray cap with 2 little metal tabs sticking out...

    803A droop adjust screw?

    Pull the top cover and get the injector(s) out. Reattach the hard line by moving the line off to the side. You should have 4 finely atomized mists of fuel spraying radially out from the tip of each injector as you crank it over. You will probably need to bleed out any air in the lines if you...

    803A droop adjust screw?

    Seeing that he mentions needing to figure out how to get the injectors out I'd say he has not tested them. I think he removed the lines and just verified fuel flow through the lines.

    Percent of rated current

    That's the % Power meter, his issue is with the current meter. The TM is available right here on this site, go to the top, click on TM then get to the Generator section and then find your machine.

    Percent of rated current

    Do you have the TM's for your machine? I may be mistaken, but I think ( like the 004-007, it may only function when paralleling 2 units together. % power works in standalone and % Current in parallel.... perhaps, but the TM will tell you for sure.

    Percent of rated current

    :shrugs:I went back and re read like 4 times trying to figure out if I had missed something.....

    803A droop adjust screw?

    Yes, the pin in the metering pump shuts off the fuel completely when the rack rotates it fully, that is how the machine shuts down. You will need to pull the cover off to remove the injector. If you have trouble getting the injector out, the thread on the top is metric, same as some lug nuts. I...

    803A droop adjust screw?

    The purpose of the test is to see if the injector is over fueling the cylinder. The metering pump does not deliver just the amount of fuel required for each power stroke. The injector opens at about 3000 PSI, sprays 1 fine mist of fuel then closes once the pressure drops below 3000 PSI. , the...

    803A droop adjust screw?

    I'd be more inclined to think that cylinder has it's injector stuck open or at least leaking badly. In my experience the perfect shim thickness on the pump is not as critical as they make it seem. When in doubt, 2 black shims seems to always work without a problem. The pump could be bad, and...

    803A droop adjust screw?

    The engine will run just fine, but you'll probably take an oil shower if not careful. The gears will be flinging oil all over the place.
