Alternator wiring help pleaseeee
I have a 240amp alternator to install in my 2000 f250 7.3. The original wiring goes from alt to starter relay. So when I upgrade the wiring do I also go from alt to starter relay and if so do I put the fuse before or after the starter relay. On top of that can I just not go to the starter relay and go straight the battery's? Please any help this is a pain.

Yes I in need to upgrade the wiring but I still just have zero idea if I go to the relay or not. I know to upgrade all the grounds and stuff like that but the starter relay is completely throwing me off as to what I do.

Below is a link with some details on how I accomplished additional wiring when I added a 160A alternator.

You do not need to wire to the starter relay first, but you must ensure safety precautions are taken.
I hope this helps.

As I mentioned in my previous post, starter relay is not a required stop in the alternator charge circuit as long as the new wires/circuits are fused or have breakers in them.
Looking at my pictures and reading some of the details noted by myself and other FTE'rs in the linked thread, you will likely be able to answer any further questions you have.
I hope this helps.

Fuses are for protecting the wires and preventing fire. Anything between the source and the fuse is unprotected. So wire size dictates the fuse locations. Also there are 20+ different ways you could route the charge and main power cables, so it would be hard to say what's best for your system. Plus there is a lot of potential damage and catastrophe involved here, so a lot of people are hesitant to offer specific advice with so many unknown variables.
