1HZ & AGM

[hino]

Any of you 1HZ owners boosting alternator voltage for AGM batteries? What's the best way to go about this
My EWD states the S wire is bridged directly to the B wire. I guess I could make a harness that includes a diode in series?


Curious what others have done; haven't found much online but I can't be the first

I have always used AGM batteries, and never altered the standard alternator charger .
It works just fine .
Only 75 ah , but you really don’t need more if your car is standard .
