on the way home tonight i noticed my volt gague seemed low while doing a steady 70 on the parkway.

like halfway between middle and 0

maybe my stereo killed it? i just replaced the battery like a month ago

so i checked on my nav unit and it showed voltage at 10.9 .. i was like omg...

when i shut the car off it jumped to 11.9

any theories?

 

That is not right man. I would have it checked out today. If it dies off completly you may get more than you bargined for. Lotsa weird stuff happens.

Good Luck!

 

im thinking the battery i got was defective..

on the way to work the voltage kept dropping.. hit 10 and everything shut off.. but the car still ran

guess il get a jump and have both tested..

any ideas?

 

Check to make sure it is charging. Use a voltmeter on the battery with the car running to check it. It very well could be the alternator. A friend of mine had the alternator go bad, it over-charged the electrical system, fried the battery and the pcm.

 

bad batteries do happen. i would def get a volt meter on that thing and check it before it results in any other damage.

 

Couldn't you just check the alternator by disconnecting the battery while the car is running and see if the engine keeps running?

 

so i had the battery tested..good..

so i bought a alternator there for 285..ugh ..but the good thing is it took all of 20 minutes to remove the old and install the new one.. runs great now lol

 

Sure, if you want to burn out all your lights and fry all of your electronics.
