just traded in my charger. had a 160 alt never really any batter low voltage problems. always seen above 12.5 now i have a new impala 150 amp alt. im seeing down to 10 volts and the system doesnt sound as good. i checked battery its good. big 3 is done already. i bought new power and ground wire for fresh install of the new car. amp setting never changed and head unit is back to the setting i had it on in the charger.
with that being said 10 amps wont make that much of a difference i dont think? between the 2 cars alts.
i do know that chevy has this battery saver thing in the car. not sure if it is a feature that cuts power to things like dome lights or something if left on. my voltage meter reads 12.5-13 not on. while the car is running its seeing sometimes 13 volts flat or sometimes 14.5 -15 volts while running. seems odd that it would be charging at a different voltages. chevy has the feature where it will cut back on power needs if not being used . and when the battery starts getting a little bit more drained then it will provide a higher charge rate. anyone ever work on an 2013+ impalas? that could fill me in f something doesnt seem right? im aso kind of thinking thatr maybe m ground is bad but the system slams loud. i dont have a volt meter right now. got lost in moving recently.
and if you have a bad ground will it cause low voltages ? i see this everywhere. but people tend to say if your ground is bad then it wont be grabbing much voltage in the first place so the voltage should still be high.
