I agree great details there, very helpful

I am not sure on this issue, I think the earlier voltage regulators did not have the diode, but later ones came with one, it sounds like yours was retrofitted. Hopefully someone with first hand experience on these will respond soon. Ike

I don't have mine installed yet, was too busy with other stuff last weekend, and we had rain all weekend this week. I know 20 &21 are F+/F-, but don't remember which one is which, for the other 4 I will need to look at the diagram while working, note there is an extra screw terminal between 24...

Could be a 3KW MEP-016D if it has a Yanmar L70 and no onboard battery tray, or a 3KW MEP-016E if it has a Yanmar L100 and onboard battery tray. Post photos and we can tell you which. The MEP-016D is a 016a/016c gasoline unit that has been retrofitted with a Yanmar diesel, the MEP-016E is a...

thanks for taking the time to look into this. Ike

What Munchies said, I think the TM says they should be checked every 500 or 1000 hours, I suspect it often does not happen in the real world. Ike

Well then the next step would be checking resistance in the windings, and to frame by megger if possible, by standard multi-meter if that is all you have.

The most common failure parts are the diodes in the exciter rectifier bridge and the output transistor on the AVR board. The most common failure mode for the transistor if for the voltage to go high. Ike

I would say it is likely not safe, I suspect you would fry the battery charging regulator, which is not cheap (around $100 new on ebay). Note it is safe to run a MEP-016D without battery since it has no charging system Ike

Yeah, it is fairly common knowledge over on the Smokstak Onan generator board, someone found it a couple of years ago. DJE is the civilian version of the DJE-M engine used in the MEP-002a (The DJF would be the civilian version of the engine used in the MEP-003a, but does not exist, closest...

If you turn the start knob back to the start position while the generator is running does the voltage momentarily spike then fall back off? There is a safety that should prevent the starter from engaging while the engine is running, also have you ever let the generator run at less than...

How are you measuring frequency? just wondering as it generally requires voltage to the meter Ike

Like Derf said, most likely MEP-002a, there is a guy over in Baytown TX that repairs them, and sells used parts, etc. if you can't find someone local to fix it. Ike p.s from its a small world department, I was just down in your area, I bought a car in Houma last Friday (found a deal online...

They are parts that ship direct from Cummins Onan, basically the same stuff you can get through one of their generator dealers, but often at cheaper prices. Ike p.s. Onan part numbers will be in the XXX-XXXX number format

One of the older 5000/6000 series Walbro pumps came on my MEP-016d from GL. We use them at work on our truck refrigeration units, they are good fuel pumps, they also cost around the same amount if not more than the Facet Gold Flo pumps. Ike

The short answer is yes, if moisture got inside the injection pump may have stuck parts, etc.

The best source I have found for fire hoses (if you don't have a brother in law that is a fire fighter, etc.) is ebay, I bought the 75 Ft 1.5 inch hose seen above for around $50, it is 20 years old, but appears to have spent its whole life in a fire cabinet somewhere and looks like new, but was...

I think there is a variable trip point on the MEP-003a output breaker, should be in the TM along with how to set for the various output modes. Ike

I am thinking part out after seeing it, that is a lot of stuff to replace, a fair amount that would be needed just to see if it runs. It also looks like most of the low hanging fruit is gone, with luck the AVR, fuel pumps and the injection pump will still be there and good. Those alone should...

If the engine and generator end is good you can gut the control box and replace it with a modern generic controller and voltage regulator (if they are missing). The real question is did they pick this one to part out for a reason (dead engine, etc.) Using cheap import controller, gauges, etc...
