The battery light n my 1992 Honda civic is flashing on and off when i stop?

Could be a couple of things, Either way you're having issues with your battery. Could be wiring/connection gone bad, a bad cell in the battery, or your having alternator issues.

Check your pos and neg cables, make sure there isn't any corrosion. If not bring your battery to Pepboys, or Autozone to have it checked. If theres no issue with your battery. Hook it back up and start your car. then remove the neg termal. If it stalls you need to replace your alternator. BTW if this is the case, the bottom bolt is HORRIBLE when it's cold out. We tried everything to get mine out. From a torch- to hammering it out- to reversing it back in. Mine is so stubborn we might just take off the brackets or pull out the motor.

Hope this helps
