does the alternator light come on when you turn on the key? If not then that light has to work or the alternator will not activate.

theres no light so what should i do to fix that


Check the bulb, it might just be burned out.

no bulb is good just checked it

coul;d it be somthing with the fuse box


Yes that circuit is fused. I can't seem to find a good diagram of an 89 or I would send it to you.

ok thanks so i just need to replace t he fuse


Hopefully yes, if the ALT light turns on when you turn on the key then the alternator should start charging.
