Just have to find out by having the charging system checked, possible bad battery or alternator, and for the ABS, you would need to get the vehicle scanned for ABS codes, which will tell you what is in need of repair and where to look for the problem.

Just got a New Battery and Alternator....


Ok, still there is something with the charging system that is not right. Usually it is the voltage regulator in the alternator that turns on the light. If you have a digital multi meter, check at the battery while the car is running, there should be no more than 14.7 DCV.

When I speed up around like 60 miles the lights comes on the Dash but soon as stop they Disappear.


That would have to be on the battery light, I can see that, even tho the alternator had ben replaced doesn't mean it working right. The ABS light should stay on, that would go out until the problem is fixed.

So Check the Alternator again????? And all the lights Disappear when I come to a complete stop...but soon as I reach 60 miles they jumps back on the Dash......Do you think it's some Electrical????


Just have the the charging system checked again. Make sure the car is being revved up to see if the alternator is putting out more than 14.7 DCV. The ABS light I suspect a wheel speed sensor, Just have the ABS codes read by a scanner. All this can be done at an auto parts store. Write down any trouble codes that they show. Mostly you are looking for the ABS codes.
