Honda EB5000 Generator issue

Hi Newbie here,
I have a EB5000 Honda generator that I picked up for a song at a swap meet. The GX340 engine had a broken rocker arm stud and worn push rod guide, which I fixed and the engine runs great, but the generator doesn't produce power. I was told by the original owner that it was producing power just fine before the engine quit and he seemed fairly honest about it.
The generator portion is a Sawafuji and has a model number of B 50 and no. A LL 6601 stamped beneath the model number as well. The control panel is also a Sawafuji and it is also a B 50 Model with a no. A LL 5798 beneath that. It has a frame number of EA7-3152768 and the engine number is GC05-3045988.
I pulled the generator cover off and blew the dust out of the windings and they all look good -nothing burned up in there. I pulled the control panel apart and there is nothing obviously wrong in there either. When I run the generator and check it with my dvm it shows it producing .2 VAC on the hot legs with the breaker on and 0 VAC with it off. Honda isn't very forth coming with its schematics or service manuals, I do have an owners manual but that doesn't help much. My issue seems very similar to this thread:

Can you help me out?

I guess there's a procedure for flashing a Honda generator (which I don't a service manual for) and that may be all it needs, but it could be worse problem I suppose....

I had the same problem with the same generator. The problem turned out to be a "de-energized field coil" due to long periods of non use.I just sent another member here the info I got from "AIRMAN", at this site, which will fix that problem (if you have the same problem).I'll send you all the info I have.PM me with your e-mail address.

if you have an electric reversible drill, start generator - plug drill in - put it in reverse - pull trigger and hold trigger and turn chuck counter clockwise to put some life back into the magnets,,BE Cautious it may start putting out right away

Does the generator have brushes? If solift the brushes and appy 12volt battery leads momentarily to the slip rings. Careful the slip ring nearest the bearing will be the negative ring.
If your unit has no brushes. put a male plug on each end of an extention cord. Open one of the cord leads and put a weatherproof light socket in series with that line. Plug one end into your gen 120 outlet and the other into a wall receptacle. Now screw a 100 watt light bulb into the socket and counto threeremove the extention cord and give it a try.
You could have several issues here and this one only re-magnetizes the rotor windings.

generator trouble

I dropped a valve in my eb5000 and it punched a hole in the piston. i have the generator shell apart but cant figure out how to get the guts of the gen off the output shaft of the motor so i can split the case.

Usually once you get the long bolt out, a sharp blow from the side with a solid block of wood knocks the rotor loose.
