110 nominal from automotive alternator ?

 Ok folks- this should be a refreshingly topical thread .

The wiring diagrams to derive nominal 110 volts from automotive
alternators are seemingly hard to find on the net . Several companies
make overpriced conversion kits usually relying on mystery modules of
epoxy . Surely this could  be done in a more direct fashion .

My current project concept is to take a lawn mower motor and have it
turn the modified alternator for simple lighting of work areas .
Yes, 12v methods do have their places , but this situation involves
existing "festoon" socket lamps that are powered by utility power in
the summer months .  IF it is practical to do this I may save 6 months
of minimum grid service @ $22/mo per year . Since this lighting wil be
needed for 3 hours at a time but only 3 to 5 days a month creative
cheap designs are welcome.

Redundant cheap units are possibily better for these few events .
Sure - I can buy a plastic ended Coleman but WHY?
I have a few delco "10si " alternators and 2 Dodge 100A truck
alternators to experiment with . Any suggestions ?

Many alternators are not built to run 24/7.....so even if you got the
voltage how long will it last in your application.
On my small steam plants ...I had better luck with elevator
motors(100-300VDC)(on larger aplication 600VDC)
than alternators.An invertor works out better for freg. and surge control
I must admit I did use a Zena alternator on my steam garden tractor
....grass and stick powered lawn mower you might say.
But then the chain saw and other electric garden tools required  that "super
duty" alternator.At times,like chipping wood and charging house
batterties, the alternator requires as much power as mowing heavy grass.

I mounted a one wire G.M. alternator to a pushmower engine, and wired it
to a 400 watt coleman inverter. I think the alternator was a 65 amp. I
also put a motorcycle battery in the loop to keep enough light to refuel
when it runs out. Put the whole shebang on the pushmower frame, and when
I'm not using it I fold the handle and push it under the bench. The
mower was free from a junkpile, the alternator was $48.00 and I think
the inverter was $29.00 from Costco. Hope this gives you some ideas.

Wasn't the battery also necessary to excite the alternator?
