    M1028 Alternator upgrade????

    Depending on the alternator, most designs utilize output from the diode trio (not the 6 diode bridge main output) to drive the field. At idle speed, most are only capable of putting out 60% of rated current before the voltage drop in the stator limits field strength which prevents overloading...

    M1028 Alternator upgrade????

    Definitely go 24 volt for a winch, you can use the NATO port up front. Remember, power is current x voltage, doubling the voltage halves the required current. You only need properly functioning 100 amp alternators for any 24 volt winch you can find. You need good batteries too.

    Autopsy of Failed Fuel Level Sensor on MEP003A

    I've got some old security system door/window magnetic switches which may work. These are soldered to a printed circuit board, through hole type soldering. So it would be easy to harvest one. Should fit in a first class envelope without additional postage. Let me know. Yes, you will have...

    003A developed sudden starting circuit short 24v to ground

    Onan made quite a few extra engines for the 002 and 003 As. As part of a reset program, new engines were put on older generators in the later 1990s. My 002 is that way. These were military standard generators, the design was government property hence the multiple manufacturers. But only Onan...

    Making a fuel tank?

    By golly that looks like a 3kW fuel tank! (MEP 016a, 021a and 026a) About 3.75 gallons.

    M37 fuel tank.........a thought

    Stainless is quite the over-kill. But if you have the skills and argon, it would work. I'm doing something similar, my little 3 kW 28 volt MEP 026C needs a fuel tank, only I plan to make it from 14 gauge aluminum, also GTAW. Only because I love to hear the sizzle of AC. And on clean...

    MEP-802A 230V Convenience Receptacle

    You have to make one. 21 amps, you need a 10 gauge conductor. 240 volts? 3 pole, 4 wire SJOW service cord with the right receptacle (NEMA 6-50 R) on one end, pigtails on the other. With the SJOW wire, you have 4 conductors, black, red, white and green. Black and red are the legs, white is...

    Making a fuel tank?

    I have an older MEP-026A that came without a fuel tank, I fixed the carburetor and it runs fine off remote tank, just have a few other issues to work through like exhaust manifold leaking and needs a good PMCS Monday. All the other parts are sourced, I just cannot find a fuel tank. So, I took...

    Alternator rebuild Q

    The regulator has two terminals plus a negative. Number 1 terminal is used by the regulator to measure battery charge state (voltage), Number 2 is used to turn the regulator on and is the idiot light. Now, if the regulator cannot determine battery charge state because the output is...

    003A developed sudden starting circuit short 24v to ground

    Probably threw a winding on the rotor of the starter. Usually happens near the commutator pads, just one break can cause the starter to have crazy high draw. Best bet is to take it to a dedicated starter repair shop, they have a growler and the know-how to diagnose. As far as the tank...

    4A032 Carburator -- rebuild or replace?

    YES, it WORKS!!! Made a quart of de-ethanoled gasoline and fired it up. Since the air filter is toast (literally), I primed it there with a tablespoon of gas on the filter element. One pull, then the pump filled the bowl and then governor kicked in. 3600 RPM. Found out the manifold on the...

    4A032 Carburator -- rebuild or replace?

    Necessity is the mother of all inventions.. I have a set of Viton o-rings from Horrible Freight Tool, the smallest o-ring is A005, it is just a little too large to fit into the float valve to replace the hard/old one that was leaking. But it fit over a 1/8" Dremel bit shaft, then turning at...

    4A032 Carburator -- rebuild or replace?

    The carb is a military standard model, since its SMR code is PAOZZ, it is not deemed rebuildable so the federal supply system never had overhaul kits. But surely there must be a source for parts, I have yet to find any. Will update if I find anything. What I need most is the float valve...

    Most ridiculous workaround ever, or a COOL idea? (Air conditioning)

    Yes, you need at least 1 ton of cooling capacity. 12,000 BTU per hour. That is roughly 3500 Watts of cooling. If the system has a coefficient of performance of 2, that means for every watt of power used, it transports 2 watts of heat out of the cab, you are still looking at 1750 watts of...

    Most ridiculous workaround ever, or a COOL idea? (Air conditioning)

    I've got a MEP-026A that I will be converting to a C (electric start model) to do the same. It will be perfect for the M1031 SECM. It will ride on a receiver hitch platform. 108 amperes of 28 volt electricity.

    Most ridiculous workaround ever, or a COOL idea? (Air conditioning)

    Yes, in my home made 24 volt air conditioning system (Sanden SD7B10 automotive compressor driven by 70 amp 24 volt motor direct drive), the stock alternators are barely able to keep up combined battery voltage above 24.5 volts. Why? The alternators have temperature compensation, the high draw...

    Trouble Starting 4 Cyl Hercules Gas Engine

    Easiest to replace the whole magneto rather than mess around replacing parts since you have not diagnosed what the problem is. Is it an impulse magneto or a straight driven? Fairbanks Morse or Slick?

    Trouble Starting 4 Cyl Hercules Gas Engine

    No spark means magneto. Too complex to describe here, the TMs do a good job. Saturn Surplus has the magnetos if you don't feel like setting point gap and dwell. Careful, they will shock the fool out of you.

    4A032 Carburetor Issue

    Well, I will have to try this. I have an MEP 026A with the type 4 engine that has electronic ignition, it starts fine but seems to flood. It has 12.2 hours on it since major overhaul. I would like to run propane but getting it proven on gasoline is important. I have a 24 volt inverter...
