jrplayer36 Posted November 25, 2009 Report Posted November 25, 2009 I was wondering if its normal for my volt to drop to 12.9 and goes back up? The only time it does this is when truck is at idle or at night with lights on. I have a 220 amp. Iam running a MB Quart 1000.1 and a kicker 650.4 and 2 12's. Any idea Quote jrplayer36
brewer_brewer Posted November 25, 2009 Report Posted November 25, 2009 what is your voltage like while driving? (above 2k) what kind of battery do you have? if it only does it at idle than i wouldn't worry about it. most HO alt make their power above 2k rpm and not much at idle Quote REFS http://www.caraudioclassifieds.org/forum/itrader.php?u=2026 http://www.stevemeadedesigns.com/board/topic/44535-official-brewer-brewer-feedback/page__p__625998__hl__brewer__fromsearch__1entry625998 "you're not allowing natural selection to work, you're like the guy that invented the seatbelt"

brewer_brewer Posted November 25, 2009 Report Posted November 25, 2009 i wouldn't worry about it at all then. at idle the alt is just spinning very slow, then add the fact that your headlights are on and you will have voltage drop 12.9 is still a safe voltage for those amps.

Nic Posted November 25, 2009 Report Posted November 25, 2009 i would add another red top to the mix... Quote Full eclipse system is next on list.. soon to gut and redo the honda as new project/rolling buissness card i miss the sound of those old school strokers on beast amps
brewer_brewer Posted November 25, 2009 Report Posted November 25, 2009 i don't see the point. if you have the money then spend it on another battery. but.... seeing as how you aren't dropping below the resting voltage of the battery, i don't think another battery will do anything. its the alt that isn't providing the juice at idle Quote REFS http://www.caraudioclassifieds.org/forum/itrader.php?u=2026 http://www.stevemeadedesigns.com/board/topic/44535-official-brewer-brewer-feedback/page__p__625998__hl__brewer__fromsearch__1entry625998 "you're not allowing natural selection to work, you're like the guy that invented the seatbelt"
slim2fattycake Posted November 25, 2009 Report Posted November 25, 2009 it depends on where the batteries float at. if it floats at 12.8 or 12.6 then it is still the alternator giving most the power. If the battery floats at 13volts then its power from the battery.

Colin - STAPUFT Posted November 25, 2009 Report Posted November 25, 2009 If your alt doesn't have an overdrive pulley, you might want to check one out.

brewer_brewer Posted November 25, 2009 Report Posted November 25, 2009 If your alt doesn't have an overdrive pulley, you might want to check one out. truth. it will give you higher idle rpm's out of your alt. and possibly even higher max amps Quote REFS http://www.caraudioclassifieds.org/forum/itrader.php?u=2026 http://www.stevemeadedesigns.com/board/topic/44535-official-brewer-brewer-feedback/page__p__625998__hl__brewer__fromsearch__1entry625998 "you're not allowing natural selection to work, you're like the guy that invented the seatbelt"

If the battery floats at 13volts then its power from the battery. even if it floats at 13 volts. he will only gain maybe .2 volts at idle.
