Check and make sure all your grounds are clean and tight...also why not get the alt tested just in case. Wouldn't hurt to test the battery too

your alternator maybe at the verge of dying.Comment

like stated above. its likely your alternator is bad.Comment

okay if thats the case why dosent my car keep a steady 14.0 voltage when its in motion thats the main problem!Comment
-
if your running alot of stuff off the battery you could be drawing more amps then the battery you have is rated.
something like this would most def work.
they also sell altenators for the same reason.

2 things... alternator connections, or belt/pulley may be slipping.
Is the alternator new?Comment
-
the alternator is like 2 months old!Comment

Ah. Gotya. Same problem happened to me. On my car, the bolt that holds the pulley onto the alternator was loose, causing the exact same symptoms. The pulley could spin on the bolt, and then produced a low charge voltage at driving speeds, (2.5k RPMs and up)
but it seemed to charge normally when at idle. (under 2.5k RPMs)
tighten the bolt, and hopefully, those problems should go away. Just make sure the alt didn't kill your battery. (it did mine)Last edited by Skidd; 04-16-2010, 10:55 PM.Comment

with a properly workin alternator you should be in the 14-14.6 range at idle.
under accessory load you should be in the area of 13.3 or more.
a fully charged battery should read 12.6 volts standing.
if you are reading ANYWHERE under 12.6 under load than you should replace your alternator if your battery is indeed fully charged.
an alternator is NOT a battery charger.
its only purpose is to recharge what little bit of energy you spent whilst cranking the engine over. they do not like being overworked due to an undercharged battery. if you overwork it you burn it out. pretty simple.
keep a strong charge on your battery at all times. this will make your charging system happy

i'm almost POSITIVE (no pun intended) that the alternator DOES charge the battery! Really what the hell else does it do... The alternator constantly charges the battery, all the time. And most cars run on the battery and the alternator is always recharging it. thats why they have voltage regulators... to keep from overcharging the battery. I will agree to an extent that you really shouldn't rely on an alternator to charge your crappy battery, but it will sure try. Yeah, it is somewhat hard on the alternator to run off of it all the time, (IE jump start your dead and never good battery) but lets face, the battery doesnt keep itself charged up, and something has to run all those lights and stereo and blah blah blah... Just sayingComment
