 +The stock GX470 alternator is BARELY rated for what the truck requires to run.  Most are older and are getting tired. ​ Average alternator failure is around 150,000 miles. ​ OEM replacement will get you close to 120A and the truck takes 90A to run.  If you add systems an upgrade is recommended. ​ There are several options to upgrade. ​ Anything more than 150A is a major improvement if you have aux gear and batteries to charge and run.  There are manufacturers making up to 270A alternators that work on these vehicles, but new cables and a protective bus bar are required.
