My trimmer head only comes off if I use a large set of pliers turning the head like the directions say. It would be impossible to do this with just my hands.

I just bought a used briggs and Stratton 10000w generator and noted a leak above the fuel line at the bushing (think that's what it's called). The fuel line looks good but fuel seems to be leaking...


Is it connected to the fuel shutoff valve? These do go bad occasionally. On some models you can unscrew the bottom to clean it out. Try removing hose, snipping a small amout off of hose and reinstalling it. See if that helps, if not you will probably need a new valve. Hope this helps!

My answer:

Not having any background info as to how old your model is or - TOTAL RUN HOURS unknown as well? - I can only give you several possibilities of what the electrical/electronics problem might be - even though I don't know the exact model # and which engine you have on your Genset.

McCulloch, Coleman, and many others as well do not mfr much of anything inside the USA today - let alone factory service anything they sell, but like with many other USA companies out there today they do private label out to a lot of mfg vendors (mostly in China btw), and the Genset gas engines are numerous to say the least. From Briggs & Stratton to Honda to Subaru and so forth...not to mention the generator heads as well. Again - all made in China.

I also don't know what normal LOAD you are putting on your Genset there, or have been putting on it previously, or at what RPM you are normally running the engine at - as to half throttle or full throttle setting?? The heavier the electrical LOAD the more heat the generator head had to dissipate as well. Is the generator venting clear and free from dust, dirt, and any obstructions? I take it that it's most likely a Briggs & Stratton 4-stroke single cyl, or else it's a Honda 4-stroke single/twin cyl engine?

Has the gas engine always been serviced properly as to scheduled fuel filter changes, oil changes, air cleaner maintenance, etc? These are just as critical so as not to burden the generator head output as well. If the generator head runs extremely HOT then you definitely have a problem there. Internal short, bad winding, etc.

Which brings me to the next point.

Since I take it that it has been running good up to now - I have a few ??'s as to how you have been running it recently, and how well it's been running generator-head wise?

Has the output voltage been really stable and clean up to this point or has it varied at lot?

Have you actually measured the AC output voltage with a good quality DVM set on the 200 volt AC scale? If so - what voltage was read? How stable was it - as to any notable variations?

Did you compare your DVM readings/findings to those listed in the Operator Manuals spec listed?

Btw - are all the output outlets totally dead? Is so then it's not the breakers at fault. Not if the engine runs OK, and at the proper RPM settings as well.

Beings your Genset is probably an older model - it just indeed might have some high RUNTIME HOURS on it. If it does it just could very possibly be what sounds like to me (and I personally HAVE SEEN this happen myself firsthand) that the generator brushes are nearly shot - as in almost worn out. Or in your case - TOTALLY GONE. If there is some brush length there, but not enough by spec then they may be getting too too hot - as from excessive current draw at point of contact, and thus the generator sensing circuitry itself is doing a complete electrical CUTOUT!!

An added protective Genset circuit feature in that the generator itself may indeed be linked to the engine as a type of REV LIMITER or CUTOUT on the Maintenance-free Magnetron® electronic ignition. Again - your operators or service manual should have a pretty good troubleshooting section in it unless you don't have that anymore or never got one if you bought it used to begin with.

If you unscrew & remove the Generator brushes, and they are indeed below the recommended length (or worse case they are indeed totally worn down) then that most likely is your problem right there.

If you choose to replace the old brushes with new ones yourself - be very careful when seating the new ones - as to their insertion and cap retainer tightening. Never over-tighten those black plastic-like brush retainer screw caps - for if you break one (hard to get immediate replacements is why), or fracture one it could cause the Genset to fail under LOAD, and that very well could do some severe damage to the generator part itself. Take your time doing it, and be patient!!

It has to be one of the scenarios listed above, as I've covered every possible cause short of a broken or shorted wire somewhere - which in that case you will have to schematic trace and Ohm out wire to wire contacts. This being the least likely scenario from my experience.

Please post me a reply as to the found problem there, and the resolve to it by following my recommendations above. Also please rate my troubleshooting fix as well.

Keep me posted and I'll follow up as well.

Best regards,

Frank

No power out to plugs


My answer:

I don't know how or where you stored your Genset there, but it the generator head got soaked with water and/or was subjected to constant moisture and/or worse case - saltwater exposure - then there's a 100% chance you have shorted out the windings and possibly burned out the stator!

There are a few things you can or should check on both the generator head and the engine if it has HIGH HOURS of runtime.

Namely the the BRUSHES on the generator head as I also don't know what normal LOAD you are putting on your Genset there, or have been putting on it previously, or at what RPM you are normally running the engine at - as to half throttle or full throttle setting??

The heavier the electrical LOAD the more heat the generator head had to dissipate as well. Is the generator venting clear and free from dust, dirt, and any obstructions?

I take it that it's most likely a Briggs & Stratton 4-stroke single cyl, or else it's a Honda 4-stroke single/twin cyl engine? Has it been serviced properly as well? Oil changes, air filter cleaned and/or changed out, fuel filter changed, Carb cleaned out periodically, etc etc etc.

These are just as critical so as not to burden the generator head output as well. If the generator head runs extremely HOT then you definitely have a problem there. Internal short, bad winding, etc.

Which brings me to the next point.

Btw - were any of the output outlets totally dead prior to the total output failure? Is so then it's not the breakers at fault. Not if the engine runs OK, and at the proper RPM settings as well.
