I already changed my battery and alternator and all fuses in the car, but the battery light stays on. I reset it too. I checked but no power is going to the alternator, how do i fix it?Ford Taurus 200

make sure the cable from the alt. to the battery is connected.

if the cable is connected. but still not getting power to the alternator, check continuity on the cable to make sure there isn't a break or anything... double check to make sure connection to the battery isn't too corroded as that will create connection issues. if all else fails you could always just try running a new cable.

I checked and cables are fine, I think i might just replace the cable in general. Thank you

Did you remove the plastic covers off the battery terminals before connecting the positive and the negative ? Check to be sure !
