My alternator just went bad on one of my cars.

while im replacing the alternator i want to upgrade the power and ground wires from the alt. to battery and battery to chassis.

how hard is this to do?

does the power wire from the alt go straight to the battery or does it branch off somewhere?

and to upgrade the ground wire do i just run the wire right off the negative terminal to a chassis ground?

i need help asap so i can drive this car again.

thanks

Well, have a look under the hood and see for yourself? :) might be handy with a worklight or a small flashlight.

Even if the main + feed from the alternator does branch off (and I'm not saying that it does)
You can add an extra wire from the + terminal on the alternator to the battery.

Just be really carefull that the wire is well unsulated and that it cannot possibly rub on anything.
If it ever shorted out on the body you would have a fire on your hands.

You could also try putting a 100amp circuit breaker near the battery.
But better to do it right to start with and never have to rely on the circuit breaker.

And I would have thought that you would need no more than about 5-6 feet of cable to get this done.
That said I wouldn't bother with more than generic OFC 4AG cable as it would only cause about 0.02V drop.
