when I first start my car it starts at 14.4-14.6 but after just a few minutes of driving it drops to 12.8 and sits there...the battery is only a couple weeks old
What car, Honda?Many new cars turn off the Alt when it is not needed in order to get better gas mileage.
changing the ecu can change it. i turn my AC on in my honda when i do my bassrace runs to get the charge out of my alt. but someone else was saying that after awhile there alt stopped charging with the AC on. i have noticed this sometimes, but not usually.In park my honda is 14.2 but when in gear and sitting idle it drops to 12's instantly... is this the same issue?I'll try the AC trick and see if that fixes it.
Any way to work around this?
wont happen. your system is on a seperate line from your ecu. so your system wont kick on your alt. sorry bro, i was hoping the same tooas long as my system forces the alt to kick in it shouldn't be an issue but there's no way I can run an m3 at a half ohm when my voltage at full tilt is like 12.78
wont change anything with a H/O alt. didnt make a difference on my dc power 220a. what year is the car?that is kinda stupid...what can I do to work around that? and what will happen when I get a high output alt?
