If it works, you could also achieve the same effect using a welder, and
probably less chance of damaging or blowing up a battery.

Subject: [alfa] Loosening stuck bolts/screws/studs etc
I got this off my Moto Guzzi list today. I have no idea if it will work
but
it sounds like a fun experiment! Gotta be better than ez-outs !

*****************************************************************************
"To loosen stuck bolts/ studs/screws in aluminum/
steel/ cast/anything else. Get 2 visegrips and a BIG battery (don't waste
yer time with some battery charger) and some jumper cables. You clamp 1 of
the vise grips to the stuck bolt/stud/screw very tightly on a shiny part
so
you got a good connection. The other vise grip you clamp very tightly on a
close by ground (don't clamp on a rear brake bleeder and use the stock
ground in the front). You connect both the jumpers to the battery and the
other end to the stuck bolt vise grip. then the fun part, you QUICKLY
clamp
the other remaining
battery jumper to the ground and there will be a BIG spark!. Wait 2-3
seconds and take it off and try to wiggle the part, if nothing happens try
again. It will eventually loosen the part, because corrosion has more
resistance than good clean metal. and you will blast the rust/ oxide out
with the maybe 4-600 amps you are putting through it. Sometimes there will
be a small puff of smoke. It doesn't
seem to make any dif on polarity. I have been doing this for 50 years
since
I read about it in Popular Mechanics. It works great on brake bleeders,
stripped carb screws, chevy manifold bolts, Honda case screws, anything
like
that."
If you decide to try this method, please make sure you place your battery
as
far away from you & your work as the jumper cables allow, and make your
final connection at the opposite end, away from the battery. Remember,
Safety First!!!
