Hm, I think if your alternator was bad it could possibly damage your battery.

How many volts is the alternator putting out at the battery terminal? When you first come out to the car, whats the battery voltage?

[jamik_69]

when i go to the car its 12.1v when the car is running its 12.1v same when i rev it

[thx247]

voltage at the battery should be 13-14 volts when the car is on iirc

check your fuses man

i changed the alternator now i have 14v when the car is on could my stereo be puting to much strain on the alternator or something like what would cause my alternator to crapout on me? any ideas

[thx247]

unless your lights or guages are dimming when your stereo is on I doubt the alternator died from that.

If your lights are dimming when you bump your tunes, talk to a stereo shop. Chances are you can just buy a capacitor and decrease the load on the alternator

Or another thing that might be mesing up your alternator could be an oil leak. I had a leak coming out the front main seal and it would go to the crank pulley which then went to the alternator. All that oil just built up and made my alternator crap out. My airbag light would be on when my alternator was low, for some odd reason, and my lights would also be dim. But, it's semi-fixed now and my alternator is still going.

does anyone know where to get an aftermarket alternator for ka that has a higher amphere rating?

Well if you have an S13 or S14 base model, then you might be fine with an alternator for a 95+ 240 w/fog lamps. 10 more amps from what I see on kragen's website. My alternator is the poop right now so I'm getting it.
