According the the manual that I once had, all you had to do to
re-magnetize the fields was to momentarily hook a 6 or 12 volt battery
across the output leads (120/240) for a second or three.


This is not correct.

To flash the field, a 12v battery must be connected between terminals F1(+) and F2(-), not the output terminals U1 and U2.  The battery must be connected briefly while the generator is already rotating at rated speed.  You should see the output come up to rated voltage almost immediately as the battery voltage is applied at the field terminals.

Again, if the generator was working when last stopped, I don't think this is a residual magnetism problem, especially since the OP already stated he tried flashing the field.  But it could be, and he might have done something incorrectly, such as reversed the battery polarity.

Must have been the translation from chinese to japanese and then to spanish then to english.

I have never flashed a field with a generator running and wouldn't due to
shock hazards, The field voltage jumping up to 63 volts suddenly and full
output appearing on bare terminals is not the way I would want to start
or stop my day. I really don't like letting the smoke escape.

Sorry Sean,

If the generator is not spinning, merely putting voltage on the field terminals will not accomplish the task.  In fact, it is further necessary to put a load on the generator in order to get the full effect.

The ramp-up to the full 63 volt field voltage is the reason I usually recommend using a good pair of insulated gloves while holding the leads against the terminals.

Not to mention wearing a tie and long sleeve shirts.

My ICD/Pacemaker wouldn't stand for much nonsense these days anyway.
After getting slapped around 6 times by it, I try not to antagonize it too
much. Shocked Shocked Shocked  Much like getting hit by lightning repeatedly.

I see your point & technically but everyone has their own way I guess.

well im not having much luck. i found a place called utterpower who has a kit to replace the dog house witch needs to be replaced anyway but i cant seem to send them email. any one heard of them?they make it look simple. the generator has 10 wires coming out of the top 2 are to theslip rings 2 are marked the rest im not sure. i cant find any voltage on any wires. not sure what to do next. thanks jim.

Jim,

I've had the manual sitting open here for a week waiting to hear back from you.  If you answer the questions I asked you in my last post, I can try to help you.
