And if you solder wiring on your car, make sure you don't use acid type
flux, because it will corrode the copper wiring and give you lots of
headaches. Get a rosin type (electronics) solder. The ammeter has a plastic
plate that the contact screws are attached to... if you solder to the screws
(or to ring lugs that are tightly attached to the screws), you can distort
the plastic plate and that wrecks the ammeter. Big wires need a lot of heat
while soldering... but if you use one of the big Weller transformer type
soldering guns, the magnetic field generated by its transformer can affect
the magnetic gauge parts in the tachometer, as well as the speedo. Do your
soldering work on the bench, not in the car, and you'll save the gauges as
well as your back.

Subject: RE: Ammeter Question
A couple more thoughts:
You will have more reliable connections if you solder them, including
soldering to the Ammeter contacts. If you can't do it, I'm sure you know an
electronics geek who can. You could use the push on contacts until you are
sure you have the polarity right, then solder them in place. Solder the
"crimps", too.
Make sure your new wiring is well insulated and not laying against any sharp
metal edges. A sharp edge can eventually penetrate the insulation and make
life just a little too exciting. Remember, there's unfused battery power
always available in this lead.
