'all this talk of wiring reminded me of a curiosity on a ship we've
seen. It's a 24r. there's a wire running from the batt. lug on the
regulator thru the f/w to a momentary n.o. pushbutton in the middle
of the panel and then returns thru the f/w back to the
regulator/chassis grnd. The job was obviously a field add on but looks
to be very old. cloth wire insulation, ivory colored button, dirt,etc.
When button is depressed(running or not, but w master on)a 12amp draw
occurs, obviously! What is the purpose of said circuit? It performs
the function of flashing/polarizing. Is this to restore flux? What
reasoning is behind this bizarre doodad? The system has performed
flawlessly without it. The dangers are clear. The button arced closed
once and some wires were getting a little warm. Ideas as to it's
purpose?'

'Maybe the idea was to polarize the generator. But it won't as wired.

Whatever its intended function was, it clearly wasn't thought out
fully. It could easily weld itself closed again (being essentially a
short to ground), and could easily start a fire. I'd pull that puppy.

'I found something in a regulator box for generators from NAPA(Echlin) that
may help ease someone's mind about Polarizing a generator.
This a copy of what if on the paper. The regulator should be installed as
normally wired.
" CAUTION: This operation is very important and these instructions must be
followed exactly.
A. Obtain a piece of wire approximately 8 inches long and 1/16" in
diameter.
B. Hole one end of the wire against screw head in the regulator BAT
terminal.
C. Touch other end of wire to screw head in regulator terminal
marked ARM for a maximum of (2) two seconds. There may be a spark but there
is no danger to you. CAUTION: Do not touch regulator terminal marked FLD or
any other metal."
The one thing that I didn't see in the instruction for cars, was
to energize the ignition switch before flashing the Field. I would think
that if the BAT terminal is not hot (12VDC), you won't get much of a flash.
I'll just throw it out for comment about flashing.
One thing that I do like about generators, is you don't need any battery to
make them work. With Alternators, NO Battery, it no workie.
