Alt upgrade from 105 amp to 250 amps

[Gregory Roque]

What cables do I need to change on a Alt upgrade; both Batts Pos, starter pos, batt neg grounds. Any thing into the relay bank under the hood? Are you aware of anyone whom manufactures cable kits? Thanks so much for the info...

It depends on the load!

I would use #2 awg Auto part stores will have them with lugs.
Or you can try a junk yard, or buy some cable at a home center or Elec. supply house and put your own lugs on
