    Got the manual ordered yesterday. I should have it sometime next week.

    Received my shop manual Friday. Now I guess it's time to sit down and do some reading.

    Well, I tore into the generator today. What a pain in the rear.

    I started by taking readings on the brush contacts for the rotor. Spec calls for 50-75 ohms. At the brush contacts it read 549 ohms. The book then calls to remove the brushes and take readings on the slip plates for the brushes. I could not get to them so I treated the rotor as if it were bad meaning disassembly for removal. Here is a pic of the generator, or what was left of it, after disassembly.

    Once I got the front cover off the stator, I could see that the slip plates on the rotor were black. I took new readings and had a result of 59 ohms. The rotor is fine. I then spent about 1/2 hour cleaning the slip plates to get them back into good condition. Poor pix from my cell phone, but here are some pix of the rotor.

    I'll be ordering new brushes and then testing again. I got the generator most of the way back together tonight. I felt that a certain portion of the reassembly needed to be done today while I still remembered how it came apart. The hardest part was actually figuring out how to get to the bolts for removing and reinstalling the muffler.

    I got the brushes and got them put on. 58 ohms through the brushes now. Still have to finish putting it back together. Probably won't have time to do that until November though. Already put in 42 hours of overtime at work this month and no breaks in sight until the end of the month.

    Today was my first day off since the 3rd. Got the generator reassembled and tested. Runs like it did when it was new. Couldn't ask for better results.

    Hallo dcyrilc , hallo to washington,

    first of all I will thank you for that brilliant posting about your successful job on the EX5500 ! And for your scary pix too !

    (sorry for my lousy english but I am a German "Kraut", writing from Berlin, Germany )

    Since my EX5500 Gene unfortunately will not listen to my prayers anymore denieing all power output now ( no green pilot lamp, no voltage on voltmeter, no power to read on the screw contacts behind the receptacle panel ( white and brown cables on contacts from rotor/stator ) I am getting prepared to go into this job too. ( Good grieff ! )

    Therefore I have some questions if that is ok here :

    1
    Do you know the Honda Part No. of those rotor/stator brushes ?
    I will try to order them here in Germany / Europe.

    2
    And do you have any idea where I might get a service and part manual for the --> stator/rotor with exact drawings of all the parts ?
    (not for manual of the EX5500 itself)

    3
    Do you know who manufactured the rotor/stator ?
    It's not Honda , and not GE ?

    4
    Did you try the "flashing" idea to wake up the alternator with an electric drill to reanimate the magnetic field of the stator before you disambled your babe ?

    5
    And do you think, that it could be enough to dissamble the right cover and the radiator, to get to the rotor/stator to change the brushes ?
    Or do I really have to strip it all like shown on your breathtakin' images ?
    Would it be really neccessary to remove the stator/rotor complete off frame, to open and change the brushes ?

    I hope that my 5 questions are not to stupid and I would be more than happy to hear from you .

    Many thanx in advance and

    Best greetings and Cheers
    from

    Hello Felix,

    Sorry for taking so long to reply. We have been moving and I just discovered your post/eMail today.

    I'll try to track down what answers to your questions that I can and post back in the next week or so.

    Again, sorry for the delay.

    Hallo dcyrilc ,

    thank you so much for your friendly reply... especially when you had to move these weeks... it always sucks. Absolutely no problem with the "delay".. Fully understandable!

    But will be more than happy to hear from you again as soon as you find the right time.

    Best greetings over the ocean

    I've never had to do that but here's a link about a rather easy thing to
    try:

    PER Notebook - Generator Field Flashing


    Field Flashing of Portable Generators

    This tip comes from the Briggs & Stratton Customer Education Department.
    As an alternative to flashing a rotor winding with a battery applied to
    the brushes, an electric drill may be used. Follow these steps to flash
    the generator:

    Plug the electric drill into the generator receptacle. (Cordless drills
    do not work)
    If the drill is reversible, move the direction switch to the forward
    position.
    Start the generator

    While depressing the trigger on the drill, spin the drill chuck in
    reverse direction. (A neighbor tried this and used a small wooden dowel that will break easily and a batterry drill to spin the electric drill in reverse)This will excite the field and the generator will now produce electricity. If spinning the chuck one direction does not work, try spinning the chuck in the other direction as you may have the
    reverse switch positioned backwards.

    Use caution not to get your hand or other materials caught in the chuck.
    As soon as the field is excited, the generator will produce power and
    the drill will turn on.

    The reason this works is because the electric motor
    in the drill will act as a small generator when spun backwards. The magnets in the drill's
    motor induce a voltage into the motor windings, which is fed back
    through the trigger, cord and into the generators receptacle. From there
    it goes into the power winding of the stator. The voltage going through
    the power winding creates a magnetic field, which is intensified due to
    the iron core of the stator laminations. The rotor intersects this
    magnetic field as it is spun past the power winding, thus inducing a
    voltage in the rotor winding. Once current flow is present in the rotor
    winding the rotor has been flashed.

    If flashing the field does not make the generator work, you may have
    additional problems, besides a lack of magnetism in the rotor. Further
    testing will be needed. Hopefully, this will give a simple way to field
    flash your generator if needed
    It worked great,that is what it needed. Thank you Todd Lambert Holderness NH

    thanx tlambert.

    But I tried that already with no success. I shurely need the brushes or a kind of a repair kit to overhaul the gene soon. Unfortunately I can not find a dealer here who knows about the distributors part numbers etc. Somebody told me to try in the U.K... but I found no contact/adress.

    And dcyrilc has obviousely not visited these pages lately.. He wrote that he has ordered the brushes some years ago..

    Thanx anyway for your kind link.

    best wishes

    felix
