Getting more current from your stock alternator at idle

[scfw0x0f]

Well, sort of.... the 270A alternator is on my list of cool stuff to do to the 4R, but not as of yet.
Currently running the "GM diode" trick on my 2019 with acceptable results.
Output is 14.2-14.5v on cold startup. That said I DO believe this mod shortened the life of my Optima Red start battery.
All other auxiliary power needs are routed through a RedArc BCDC 1225 that manages the AGM auxiliary battery at 13.2-13.5V.

[MENTION=647615]lewdog998[/MENTION] and [MENTION=144561]DCPower_Anthony[/MENTION] may have worked out how to put a DC Power Inc 270A into 2018-2021 (at least) vehicles. See the thread at High Power Alternator install

Did defrostersin the olden days just operate with more moisture?

In the real olden days there was no a/c so you defrosted with humid hot air, it just took a bit longer to clear most of the windows
