    How to check the frequency meter

    Yes, Pete, there are two types of meters corresponding two different transducers. Mine is Technology Research Corporation of Clearwater FL, FSC 60177, model 72-5019, part number 10125. My friend's 003a has the same unit but batteries were dead so no live test. But my ohmmeter worked as a...

    How to check the frequency meter

    Good to know, I've traced the circuit diagram and see the same. This is but half of the frequency indication system, the other half is the meter. My meter is corroded beyond what I can repair, the movement appears to be electrically intact (moving coil, permanent magnet) and since the...

    MEP 004a stuff I couldn't find by searching

    If the fuel pumps are the cylindrical type, they have a strainer on the bottom, 9/16" wrench removes them. Also, if the gaskets there are leaking, no fuel delivered, just clicking. They have a magnet in the bottom cap to trap rust too. Clean the strainers, (Pro Shot Copper Solvent IV gun...

    How to check the frequency meter

    I'm working on the answer. Basically, the transducer converts the frequency into a small current, between 4 and 20 mA. A tiny current but enough to swing the needle. So my best guess based on the ranges of 55 to 65 Hz (10 Hz) and 4 to 20 mA (16 mA) would put the 60 Hz current at 12 mA. You...

    MEP-002A Multiple Issues...

    I don't know how handy you are but you should be able to fix it. Unless it is badly corroded/broken. I've fixed the ammeter and fuel tank gauge on my 002a even though these are sealed. The frequency meter is beyond repair, all damaged by water. If you do attempt, do it in an empty room and...

    MEP-002A Multiple Issues...

    Yes, you are on the right track. Fuel pumps should flow through the injection pump and back to the tank. Take the cap off and listen. Be careful, a shorted coil in a pump could draw considerable current. Check wiring before to eliminate short circuits.

    MEP-002A Multiple Issues...

    S1 term 27 is contacted to terms 11-13-15-25-28 when S1 is in position 5 which is start. Have you checked the battery charging fuse?

    Mep 002A Battery Indicator

    Yes, the battery/charging indicator is indicating correctly. It is a DoD standard item which works well enough. Running the generator outside of 1800 RPM will generate power with frequency outside of 60 Hz, this can damage motors, transformers and the like. Better to run it slower as many...

    Mep 002A Battery Indicator

    That is attractive. Now if it is digital with decent resolution (1/4 Hz), it would be fantastic.

    Mep 002A Battery Indicator

    The "alternator" is unlike any other military vehicle in that it is a permanent magnet rotor, much like a motorcycle's charging system. IIRC, 7.5 amperes maximum. As the voltage approaches 28, the current is shunted to a resistor. Like a motorcycle, the regulator dumps a good bit of this...

    MEP 002a fuel tank woes

    I like metal work. Just don't like rust. It is now holding water. Was not able to locate powerful acid flux so I used a toilet bowl cleaner that has hydrochloric acid, it worked great. Even on the steel rivets since I couldn't find all copper. Now to make sure it is sealed, then pickle once...

    MEP 002a fuel tank woes

    Back on it today. I see a problem with the drain on the tank, the tank where the drain attaches was concave, meaning it will not drain all water in the tank. I reversed this with a piece of pipe through the fuel gauge port, placing the tank on a layer of sand to cold form a positive sump.There...

    Mep 002A governor linkage broken.

    Good call on keeping the engine speed near 1800 RPM because the injection pump has fixed timing, unlike automotive diesels with centrifugal or better adjustable timing. With fixed timing, injection is optimized for one speed range. Running it at slower speed makes injection too advanced for...

    MEP-002A Failed on it first real test! HELP! (again)!!!

    The governor works on centrifugal force (centripetal acceleration, tangential velocity squared divided by radius). Bearings could be dirty. If the injector pump control arm is near the stop limit screw under no load, the pump has and internal leak. If the exhaust is smoky, the timing is off or...

    How did you pick up / move your MEP 002

    Loading? Come-along+mesquite tree. Offloading? 2" binder strap+binder winch/ratchet and a turn-around roller on the end of the trailer. I mounted 10" pneumatic wheels on 4x8" timbers which slide into the forklift tunnels, two fixed on the engine side, two castered on generator side. The...

    Interesting. Sluggish governor internals?

    Mep 002A governor linkage broken.

    Test for voltage. That will show intent of the stop solenoid, voltage there means fuel can get to the injectors. Injection pumps are built with tiny clearances, diesel engines that aren't run often can varnish the internals, in this IP, that can cause sticky operation. Since the power...

    Mep 002A governor linkage broken.

    You have a sluggish control collar. You can fill the pump with B12 Chem Tool and work the control lever until it freely moves from stop to peg(limit stop). It should "click" at each stop. Any sticking is bad. Be sure to blow out the B12 and prime with clean fuel. The stop solenoid should be...

    MEP-002A Failed on it first real test! HELP! (again)!!!

    No, injectors are fine. The problem is the IP's control collar is binding, preventing the governor from calling for full fuel. Timing is fixed, only injection quantity modulates power. Being stored for 10 years without operation and using the crappy diesel varnishes the fuel system. And...

    MEP-002A Failed on it first real test! HELP! (again)!!!

    Joe, did you have to sow seeds of doubt in my mind over my 002a :shock:? I checked governor and control lever action, the latter was STUCK! And it is a major pain to remove. The governor's spring and centrifugal forces are slight, this lever must move freely. First, remove the stop solenoid...
