anubis Posted December 20, 2009 Report Share Posted December 20, 2009 ok when car is off its 12.6-12.7 but when at idle i went from 14.4V stock to 14.8V and now 15.4V! wtf??? all ive done is removed the ac compressor and its jumped up the two times since thus the 15V range now and no big 3 yet. what could be making this happen and do i need to worry? car: 99 olds aurora alt: stock 140A plus big 3 is gonna be more time consuming than most cars since my stock location of my battery is under the seat with big fuses ill try to take pics or vids Quote 1998 Monte Carlo Z34 Stock HU but have replacement Stock Highs Stock Electrical BTL 18 sitting naked AP1500D Link to comment Share on other sites More sharing options...

tacomabanga1986 Posted December 20, 2009 Report Share Posted December 20, 2009 if u unhooked the battery for a while n then hooked it back up the alt will bost the voltage till the battery is charged again this is how u can tell if a battery is charged or not from a battery charger, if the voltage goes from 15.xvolt to around 12.0-12.6 WHILE STILL HOOKED UP the battery is charged i had not known this till i at playin around with my truck and i had both my batterys unhooked n when i got done with my big three my voltage was at like 15.8v then went down to 14.4 or so its normal, its the internal voltage regulator that does this, i just wished i knew how to tap into it n set it to w/e i wanted to n leave it at that anyways hope this answeres ur question Quote here's a link to my system 99 toyota tacoma , 2 mtx 8000 1504's in a sealed downfire , 1000w memphis amp here's a link to my other system my 90 geo prizm test car heres a thread i got of new songs u can dl that are legal = Some Good Bangage/you Can Dl These Free And Legit Link to comment Share on other sites More sharing options...

tacomabanga1986 Posted December 21, 2009 Report Share Posted December 21, 2009 and if ur voltage doesnt go back down to around 14v after a while ied have it checked cause the voltage regulator might be bad n could burn up ur alt if u aint carefull i kno mla moduals boost voltage n what knot too but it was made for that reason, if ur voltage doesnt go back down it might go up higher n burn up something i think mine ran at like 15.6v for 2 days i think n then went back down to 14.4-14.8 just in cold weather let ur batterys charge good befor u start wangin on ur stereo, they tend to loose voltage due to cold climates than hot-warm Quote here's a link to my system 99 toyota tacoma , 2 mtx 8000 1504's in a sealed downfire , 1000w memphis amp here's a link to my other system my 90 geo prizm test car heres a thread i got of new songs u can dl that are legal = Some Good Bangage/you Can Dl These Free And Legit Link to comment Share on other sites More sharing options...

Hotdog Posted December 21, 2009 Report Share Posted December 21, 2009 Does your alternator wire go to a fuse box under the hood then to the battery from the fuse box?
