With the engine running, check voltage across the battery terminals with a multimeter. You should see a steady 13.5-14v. If it's down around 10-11v and fluctuating, you probably have a bad ground somewhere. I know you just replaced the battery, but check the terminals anyway, especially where the negative cable connects to the chassis. Might be a good idea to remove the nut and scrub the end of the cable and the contact surface on the chassis with a wire brush. Also, this is probably your culprit but check the other things listed anyway. Look under the car, just inward of the front passenger side wheel well. You'll see a ground cable going from the passenger's side motor mount to the passenger side frame rail. Remove it and scrub both ends of the cable as well as the mating surfaces. Best of luck! |
