Figured out how to keep steady voltage

Cool, Thanks.

Unplugging tonight. I hate the voltage change. Old school thinking in my brain says something is wrong

This explains why for years the headlights would flicker/dim on another GM car with this nonsense. I love the luxuriousness of these new trucks but wish they were as simple as a '73 or even an '87 Suburban.

While doing this mod, do you have to disconnect the battery?

Does this keep the voltage around 14 even at idle? I had a buddy unplug it on his 13 sliverado and his dropped to 12.6 during idle.

It did, I'll be checking this on the Silvy now...

I don't have any type of audio or electronics but my headlights and interior lights dim quite a bit at idle.
I notice my volts drop a bit while driving to.

I installed two XS batteries figuring this would help.
Then, I thought it may be my alternator. Could it be?
Or, would unplugging this do the trick?

Thanks

Alt output drops at lower rpm but not that much, when the alt is about to crap out is when it really starts dropping....if you have to keep it revd up to stay around 14v something is wrong, alt going bad, batt going out, loose wires. First thing i used to do in all my plow trucks was to run a 10ga wire direct from alt to pos on battery it always kept steady voltage... as opposed to going thru factory bs splices and long runs around the engine bay...
