    Mep-802A crank no start, high crankcase pressure

    Are you getting any smoke at all out of the exhaust? If the issue is low compression you would typically get a bunch of light gray smoke. If you aren't getting any smoke at all I would still suspect no fuel despite no results from the starting fluid. I'd do a little more digging before pulling...

    Mep-802A crank no start, high crankcase pressure

    Could be rings and I've seen my fair share of stuck valves, often times not frozen but just not seating due to excess carbon buildup around the valve and it's seat. Could be several other issues too. With that much pressure in the crankcase just spinning the motor over, I'd lean towards a piston...

    Mep-803a

    Definitely looks like a cool, simple load bank solution. I think Guy's point is that you and I know enough not to touch it while in operation, but kids get curious.... and wildlife just doesn't know any better than to bump into it or stick their face in to investigate the water.... assumingly...

    Bought another non-running 802a, begins to start, then falls off (Now an excessive vibration fix up thread) (SOLVED)

    What size fuse did you put in there, was it 30A? I've seen them blow if the batteries have an issue, but if batteries are good and you had a 30A fuse in there and it keeps popping you will need to do a little digging.

    Mep 803a fuel injection pump

    One thing I would try is take one of the stiff pumps and compress it just about 1/8" or so and see if the lever frees up. When they are installed there's a slight amount of preload on them. I have see some that are stiff ( a little stiff ) in their free state, but free when compressed slightly...

    Electric Priming Pump on MEP-804A

    Would appreciate some help, preferably without a scolding to read the TM. I have too many vehicles needing work to do much TM reading. Guy's not scolding you... he's just stating the facts. You should never be too busy to read how to operate and fix these things correctly, because NOT reading...

    Share your latest GP auction MEP treasure!

    Obviously you too have caught Green Machine Fever.... once exposed, it multiplies and quickly consumes you. ( and your wallet )

    Mep 802A no power to lugs. Power to receptacle.

    So I believe he means he is able to "close" the contactor by holding the switch, but it doesn't stay closed. "Trip" was probably not the best term to use... ;) Did you check the switch to ensure the diode is installed ( correctly ) and you should also verify the diode is good. If that all...

    MEP803A Wont Shut off

    Open the side door and see what the fuel shut off solenoid is doing when you turn off S1 Does it extend all the way out, towards the radiator? Is everything still attached correctly? Did the screw and knob fall out? Does the lever on the side of the motor rotate fully counterclockwise until it...

    Freq Meter intermittent operation Mep002A

    It's a very simple system so start at the left side of the transducer, do you have 120VAC or so coming into the transducer? If so and the transducer is known to be good, the only thing left is a bad or stuck gage and / or a broken wire. Check for power in first, then we will move on accordingly.

    Just when you thought you've seen it all!

    Glad I could help you out in a time of need. This machine sure has had it's share of hidden secrets, the governor spring being only one of them! Can't wait to see what surprises Gen#2 holds for me! Did you really need help with them, or is this all a secret test?? ;)

    Mep 002a low power and low throttle response

    I don't think you will find anyone selling a plunger, plus as mentioned, the plunger, body and metering block are a matched set and not intended to be interchanged. Before going much further I think we need to confirm if you really have a problem with the plunger or not. I do have a good PSU...

    802A

    Definitely need to keep an eye on things. There is always a possibility it was coolant and not water from the environment. We've also seen sets with water in them because they were underwater in a flood. I'd change the oil and filter and put a 50/50 mix of oil and ATF in the crankcase. Run it...

    Mep 002a low power and low throttle response

    It is one solid piece of hardened steel, so it will not have twisted or anything, but it does look odd, however I can't confirm they are supposed to be perfectly aligned without one to compare it with. If you take out the drive pin does the round shank come straight out from the rectangular...

    MEP-803A wiring to a 50 amp plug (several questions)

    I think you're talking about the bonding strip in the lower right corner of the lug panel, remove it to separate neutral from ground when running a 4 wire hookup.

    Mep 002a low power and low throttle response

    Actually never mind, I was looking at it wrong. You have it assembled correctly.

    Mep 002a low power and low throttle response

    roll the plunger over 180 degrees and take another picture, I think you have the drive pin in the wrong side of the plunger, but I don't have an old PSU plunger here to compare with your pic., just going by memory.

    Just when you thought you've seen it all!

    Well, I have an interesting story for you folks! Today I took in a newly acquired 802 that belongs to a friend, in an attempt to try to give him a hand. He said it runs and makes power but won't rev up to 1800 RPM. He dropped it off this morning, and of course, with about 1,000,000 other things...

    802A

    Does it have an exhaust flap on it, or is it missing? If it's missing the flap and you have water in the oil you are probably in for a bit of work!
