IN, and thank you!

Well, I think you may be right, and perhaps I mistakenly concluded the service outlets weren't putting out much current. I took apart the transfer switch at the house and found something that looked like it could cause a bad connection on one of the hot legs. I soldered it with a little torch...

How can I test for this? Which is terminal 6? I will check the manual, but you may know right away.

Ok, I stripped the plug off an extension cord and hooked it across L0 and L3, then L0 and L1. Same results: 120.2 V before turning on load. Turn on 5hp shop vac, drop momentarily to about 110V, then recovered quickly to stabilize at 118.5 volts. Low power on vacuum suction. Added halogen shop...

Checking now. One more test: the service 120V outlets are dim regardless of the position of the reconnect switch (disconnected from lugs to test this). Jim

So I think this is definitely a generator problem and not a house wiring problem, because the AC outlets on the generator itself do not produce enough current to run a shop vacuum. It comes on, but doesn't have much suction. A shop light plugged in is dim. Naturally, I waited to hook this up...

Is there a continuity test I can do on the reconnection switch? Does that even make sense as the problem area?

There is good continuity across the AC circuit breaker on all poles.

I am looking at the meter on the front panel. Not very accurate, I know. Also, keep in mind that the 120V outlets on the generator do not light a bulb to full brightness either. I'm stuck...

Update: when I switch on the AC circuit breaker on the generator and turn on the house load, the current meter goes from zero to about 25%. The engine lugs slightly but voltage does not drop. Frequency drops about 2 Hz. Lights in the garage come on dimly. I checked at the plug I connect to the...

Hey guys, working on this now. It must be 1800 rpm (sounds like it), but also I can dial it in to a steady 60hz output frequency as measured by my multimeter. i was wrong about the voltmeter switch. In the far right (L3-L0), I get a nice, steady 120V. Second from right (L3-L1) I get a steady...

I failed to answer one question: I have the switch on 120/240 single phase.

Thanks, guys! This makes sense. The volt meter shows 240 when in the far right switch position, which I believe is L1-L3 voltage. Interestingly, it shows about zero in other positions (I think those are L1-L0 and L3-L0, correct?). That would seem to imply the problem is on L0, right? Wouldn't...

No, it doesn't seem to.

Hi guys, I tried to use my 002a and have a problem. The unit starts and runs just fine. When I had first bought it and set it up, there was a short at the starter positive lead against the shutter box. When I hooked up the batteries, the VR capacitor burned up and the ground strap burned. I...

The generator has an 80% power factor. Power factor is the ratio of the "apparent power" to the "useful power". In order for have 10kw available to the load (useful power), the generator actually needs to generate more "apparent power". Your generator, at 52 amps X 240 Volts generates 12,480...

That is definitely the lesson from this, and a great lesson for your kids. If I hadn't just stuck it on there, I'm sure I would have gotten a nice big spark off the battery terminal. I'll fire it up later and see what the charging voltage is. Hopefully I got lucky and only cost myself time, a...

Thanks to all of you for sharing your knowledge about these great old generators. I bought an MEP-002a from South Dakota after reading these forums and the TMs and learning a lot about the units. My generator is a 2007 rebuild, with 12 hours on the clock. All new hoses, hose clamps, and wire...

Oops. Double post. Edited to tell you about my generator. Appears to be fresh from a depot overhaul, with 12 hours on the clock. Recovered from South Dakota in my pickup. The unit came complete with a slide hammer and new battery tie downs, and a canvas bag full of goodies I haven't examined...

Hey guys, I'm working on getting my first MEP running (an 002a) this weekend. How do you flush the fuel lines? Do you just disconnect the line at the injector pump and let the pumps run in prime mode? Is there a solvent that can be used on this flushing to condition the lines and remove any...
