Most guys I know have the battery in the rear of the car
so the weight isnt really a bad thing(but yes, weight
is weight).. I've never had any issue with the 12v
system and I dont plan on going to the 16v... I've
tried multiple things when it comes to the charging
system over the years, no alt, alt with a switch on
the field to turn it off and it never made any difference...
I havent even put a charger on my car in years...
the last time I did was when I unplugged my alt output
to plug my timing light in and I forgot to plug it
back on... now I use the Flaming River light so it
has its own power
NOTE
that same battery has been in the car for at least
8 years
