Hello Programo5:

At 15 dollars each, and used sounds like there are not in premium shape.

It may be possible to have them rewound for a higher current, for
running a 4 or 8 pill amps. My 4 pill 2SC2789 amp will draw 75 to 80
amps with no problem.

A 105 amp alternator may have a higher peak current capability than
just 105 amps. I have never measured it but I would think it would have
say a 10 to 20 percent higher peak intermittent rating. Anybody know
about this or measured it?

Most Installations I have seen with a 8 pill amp have had only a 100 amp
or so Alternator. So when the 8 pill amp wants to draw say double of
what a 4 pill amp will draw something like 150 to 160 amps or more, the
Alternator will put out its maximum output current, but the voltage will
drop, and the battery will start to put out current. And when the amp is
unkeyed the Alternator will try to recharge the battery, at a rapid
rate. Its possible to get behind the curve of the Alternator charging
the Battery, and the battery can over heat and possible be damaged with
high current charging over a long period of time.

A lot of guys use large batteries. I think the large batteries is a bad
call as the Alternator should be able to source all the current, to keep
the voltage as close 14 volts under load to keep the out put power up
there. And if a second Alternator is installed it can be wired to also
charge the vehicles battery or run the electrical system should the
stock Alternator fail.

When the guys volt the amps, running more than 14 volts to increase the
out put power even more, then you must have one or more Alternators that
will have the current capability to maintain the higher voltage. The
Alternators outputs can be connected together as they are diode isolated
internally, so feedback from one alternator into another alternator will
NOT happen.

One of the really neat installations I saw at one of the shoot-outs, was
a Bird Watt meter modified to also be able to indicate the amplifier
input voltage and current. And many guys have a separate volt and amp
meter on the dash to indicate the voltages and currents, pretty neat-o.

I have a chance to pick up like 8 used 105 amp Leece Nevilles for $15 a
piece..Is this to low of an output to make it worth grabbing them and
attempting to turn around and sell them?..Thanks
