alternator cant keep up or your battery is failing or both lol
wait i think its your battery cause at low rpm the battery runs shit when the alternator cant keep up

edit: find some place to do a battery load test...thats the best way to tell if your battery is weak...i think a local parts shop will do it for free but im not sure? then if your battery check out then you would wanna see what the output of the alternator is

Ok so I should charge my battery all the way up and if that does not work get a new battery?

[amicheze]

advanced auto on 13th does free battery checks. try that. if its not that then its definitely the alternator. id say its more likely the alternator not being able to keep up at low rpms, but im not 100% sure.

[Bryce]

OK I will do that thank you.

[My NOva]

yeah advanced does free checks so does auto zone have u checked ur ground i had the same problem with my cd player/subs fixed ,y ground and it was fixed u should try that

[Guest]

I have a similar problem but just all the lights go dim.

its probably just your battery...if it was ur altrenator...it woiuld make ur battery die...or it usuually does....just get a capacitor and you will be able to tell how many volts you are running!

amen...get a good size one tho...or get a batcap, ive heard good things about those. one thats reasonable used on ebay is a 15 farad made by alumapro (kick ass shit!) and runs around $225ish...considering the average 1 farad is $50 or so, u r getting a lot for your money....thats just my .02

[My NOva]

yeah caps are the way to go i got a 2.2 cap in mine runs great im running from 12to16 on mine

If I were you I would buy an optima red top. $150 3 year free replacement warranty, cant go wrong. I have one and its the best battery money can buy IMO.

[My NOva]

those are awesome batts i had one "key word here"had" but it got stolen along with 600.00 and some odd dollars gone

[Guest]

dont waste the money on the red top get a yellow top...i can get ya one for the same price as the red with a lifetime warranty.

[My NOva]

for some cars the yellow wont work it will over heat the car its like the same thing as puting a 12 volt battery into a 6 volt system it will over heat " i know this cause i did that to my 52 chevy dump truck i got the truck out of the way"...lol

[Bryce]

Yeah this is my winter beater I'm not looking to spend $200 on a battery, I will just go w/o subs if I have to spend that much money.

[PSiedTSi]

just buy a cheap $50 advance autoparts battery
