I have to Volvos, a 99,C70 and a 00, V70 they seem almost identical when you look under the hood. (Thats the reason why I post this in two places)



The alternator seems to be overcharging the battery making it very hot and I can smell the battery acid after a few minutes of driving. I just put in a new battery and hoped this would fix the problem, but the car still is acting up the same. The only light that came on is the "alternator is not charing" light. (light #13 in the manual. Shows a battery with a + and a -) Volvo should just have skipped #13 and moved right to 14.....maybe thats the reason I had to do so much work on my car the last year.

I guess I have to bite the bullet and have the alternator changed, but I was hoping there would be some kind of cheaper fix like maybe a voltage regulator or something else that could be causing the problem.

I have changed the ABS module myself which I felt was fairly easy. How much harder is it to change the alternator?

I have been looking for a "do it yourself guide" on this forum regarding the changing the alternator but have not found one. Any links are much appreciated. I seen a very nice guide about changing the ac system. Something similar regarding the alternator would be great.

Thanks!!

 

Most likely the regulator is bad.
