Charging wire from alternator...
While I change out my alternator tomorrow I was thinking about replacing/upgrading my charging line from the back of the alternator.
I have a few questions:
-Where does the wire run to? Straight to the batteries?
-If I replace the OEM wire will the warning light in dash still work properly?
-Does anyone have a wiring diagram?
Thanks!

It goes into the main engine wiring harness, and then across the top of the engine, into the PASSENGER side battery. What most do when upgrading the amperage is to run a second 4ga wire off the same post to the other battery. I did just this when i put in my 220a alternator the other day.

Electricity is going to take the path of least resistance. For instance, a short happens instead of all of it going through the smaller grounds, the brunt of it will go through the shortest, largest ground.

Yeah, i got the shiney one from DB. Sucks tho, has yours started to turn gold? from the heat i guess. Anyway yeah the ******* that helped me hook up the cables (who insisted on doing it for me) touched the hot cable to the alternator casing a few times, not shiney there anymore.
