silvr04M3 · Mon, Dec-06-2010, 03:05:32 AM

hey guys so about 4-5 months ago my battery light was comin on at over 4500 5k rpm so i bought a rebuilt alternator from a forum member and worked fine and today the batt light started comin on agin only under 1500 rpm tho once i get goin it goes away...

does it ever die on you?

Do you have towing insurance? Motor club?

If not - I'd park it until you replace the alternator. We have no way of knowing if even when the light is going out if the alternator is adequately recharging your battery. Nor do you.

Might be OK, might not. Balance the cost/benefit ratio yourself based on your situation.

If the light is on that means the alt is either dead or on it's way there, either way it's not working at 100% and will only get worst.

I would monitor the system voltage, and if it's low, don't drive the car. You can do a lot of damage to the electronic components of the car by not giving them enough power to run efficiently.
I posted up how to watch it recently in here:
