where should i look
i have a 1998 ford taurus. the alternator wont charge the battery, and the
dash light wont come on. i replaced alternator "which tested good" and also
the battery,and checked the fuses but i still can't find the problem.
I think the alternator is good, I think you have a short that is draining the battery when the car is off. Allot of people don't have the aptitude to test electrical circuits. Here is a easy way to find and hone down a short in a car. It is very simple to do.... copy and paste...https://www.youtube.com/watch?v=n5FJDgcdii8
The Alt dash light must come on when you first turn on the key, that is part of the exciter circuit for the alternator. Could just be a blown bulb.
Check the ground wire going to the vehicles frame.
