    Fixing up my MEP-803A"

    You could try adding 1 more black shim to #3 and #4 and see if that changes the sound by delaying the injection point a few degrees. I would not change the rotational position of your temps are pretty consistent. All that does is vary the amount of fuel delivered with each pulse. A trick to help...

    MEP-804A Diode Ring Destroyed

    Hi Evvy, were those bolts 3/8" or 7/16"? They look relatively small in the picture so I'm surprised your impact wasn't up to the challenge. It looks like you have lock nuts on there, but still shouldn't have been that big of a deal for a decent impact. However, from experience I know there are...

    Gen sets MEP need advice

    As for the 120V single phase, yes you will have 10A available at the outlet. You also have 120V single phase available between any of the 3 hot lugs and L0 as well as 208 ( not quite 240 but close enough for most devices ) single phase between any 2 of the hot lugs. If you're using 3 phase for...

    MEP-804A (PU-801) Fuel Leak

    And as a word of advise, if you end up going back with the original style well nut, searching around on the internet for A3816 you will find dozens of "Cheaper" listings for "Equivalent" 3/8"-16 Well nuts from PoP Fasteners and Hillman etc. , but do not buy the cheap replacements! Stick with at...

    MEP-802a contactor

    Not sure I quite understand Dewie's previous reply.... On an 802, the 5Kw mark is at 80% on the load meter, and I thought the 802's are rated at 26A at 240V , so wouldn't that be 6240W ( at 5000' 100F or whatever condition is listed on the data plate ? ) Maybe I am misunderstanding your...

    Mep-002A Bridge rectifier R1 burnt

    AC box is off an 002. I know the circuit breaker is different, as well as the number of loops through the CVT but I also notice the schematic in the 003 TM shows the ac outlet being wired right to the AC select switch, but the schematic plate on top of the 002 shows the wires going to TB2...

    Mep-002A Bridge rectifier R1 burnt

    Well, a bit of good news tonight. Just swapped out the AC box and everything seems to be back to normal. Voltages are all correct and no stinky smoke pouring out anywhere anymore. Looking closer at the original AC box, it looks like all the heavy AC wires in the thing are discolored. Instead of...

    Mep-002A Bridge rectifier R1 burnt

    Status update: Last night was an interesting time, I taped up the mouse-damaged wires in the AC reconnect box and went ahead with the initial start-up. This set has been sitting for well over 25 years.... with the notorious PSU pump in it! Cranked it up and she fired up almost immediately...

    Mep-002A Bridge rectifier R1 burnt

    Ok, so I will begin by starting the machine and seeing what happens, keeping an eye on A4 and the generator output. Then I will disconnect #17 off the regulator, isolate it and see the result. Thanks for the guidance!

    Mep-002A Bridge rectifier R1 burnt

    Turns out the exciter coil is good. 34.6 ohms. Last night outside in the dark I apparently put the DMM on the diode setting, which is right next to the 200 ohm setting! But when measuring correctly, both at the plug on the back of the AC reconnect box and TB3-5/6 both yield 34.6 ohms. So it...

    Mep-002A Bridge rectifier R1 burnt

    Got it Peter, I know what to do next. I will give another update as soon as I have another change to look at it.

    Mep-002A Bridge rectifier R1 burnt

    After checking a known good 002, either I'm measuring it wrong, or the DMM Vs. wheatstone bridge measurements are completely different. I also got .062 ohms when checking another gen, so perhaps I'm doing something wrong with my measurement. I do have a few other machines I can check as well as...

    Mep-002A Bridge rectifier R1 burnt

    Thanks Peter. I took the plug off the back of the AC reconnect box and it appears the exciter stator winding is about .065 ohms. Looking at the TM I believe they are looking for 3.6 ohms +/- 10% using a wheatstone bridge. Assuming the wheatstone is similar to a DMM I think I need to dig...

    Mep-002A Bridge rectifier R1 burnt

    Hello folks, I was wondering if anyone has had any experience with a burnt R1 resistor on the A4 bridge rectifier board in an 002 / 003? I recently picked up another nice 002 from a nearby estate auction, on a tip from another SS member. The owner told me he acquired it while stationed at Ft...

    802/803 fuel pump fittings

    Interesting... I just ordered some ( fairly heavy ) truck parts from Rock Auto and they shipped from 2 locations to RI for a total of around $30 for the 2 big heavy packages. Guess they keep their fuel pumps stored in their Alaska warehouse! Now back to the 802... so if your friend's wife ran...

    MEP-802a contactor

    You are probably correct in thinking the contactor was stuck, if you do a little looking around you will see that several of us have used the rubber mallet rework to "Fix" stuck contactors in a pinch. If everything inside is clean and corrosion free I would say put it back together ( ensure the...

    802/803 fuel pump fittings

    L.I.T.D is correct. I've used quite a few Airtex E8135 to directly replace the older Cube style Facet pump. It will drop right in using the original fittings. To replace a failed E1074 is slightly more difficult because the E1074 has a permanent Right angle outlet on it, so you need to also use...

    MEP-804A Diode Ring Destroyed

    To comment on 87cr250r's Overspeed question, while ANYTHING is possible with these generators, I believe that machine does have over speed safety's but in addition, I would suspect that a correctly manufactured diode ring would be able to handle much more "overspeed" than the engine's...

    INIpower IG-1000

    Probably not a big deal at this point. Those auctions are all closed already. I believe the rule is intended more for posting or discussing upcoming auctions, not so much closed auctions. I agree... I would never pay $2000 ea. plus fees ( that $10K auction was for 5 units ) for something that...

    MEP-003, What have you done to prepare for this new winter season

    Sounds like a super thorough winter prep. I wouldn't be surprised if the fuel additive helped smooth things out a little. Lately I have seen lots of issues with fuel pumps , IP's and injectors on the 002/003 series beginning to have problems with gum and sticking after just a few months...
