View Full Version : Battery light on

02-10-2005, 10:49 PM
Hey guys,
My battery light was flickering a little bit but now stays on. I turned the car off then turned it back on. It has been stutering a little before it actually starts but it has been like that since i brought it home. Any ideas? Do I just need a new battery or should I just charge it back up?

Thanx for the help.

Your alternator brushes are probibly worn out. Your brake light probibly turns on too because it's on the same circuit. You can either put new brushes in the alternator (about $20 in parts) or a new alternator. I would also have the battery charged then tested.

if my alternator stops working while im driving what will happen. I am at school now and have about 10 -15 miles to drive home.

Well.. um.. your battery will begin to run your car.. who knows how long it'll stay running until you drain the battery and then it'll stall and it won't start back up.

Just don't run the stereo or heat/ac and etc. to conserve on battery life.

I'm going to bet that 10-15 miles will be fine.

ill just prepare for the power steering to fail if it stalls. Ill be fine Im sure but it still pisses me off.

make sure to keep your rev's up! My car died two weeks ago with the same problem. When your coming to a stop drop the car into neutral and keep your rev's around 2grand and it shouldn't stall out. I was slacking and let my rev's fall below a grand and that was all she wrote until the two truck driver arrived!

if you don't have lights or anything on you can go longer.. simply because your engine doesn't really use much power at all for the ignition or anything.. your alt should stay at atleast 11v.. that's enough to get you there.

Did it boost correctly on just the battery?
