mediabandit Posted March 19, 2007 Report Share Posted March 19, 2007 hey guys,my battery keeps dying in my 1991 lumina z34,so i am thinking it is the alternator because i replaced the battery with a brand new one and it still drains and stalls from time to time.i need to know where the alternator is on the 3.4l dohc v-6 and if it is a great task to remove/replace it or am i going to have to take it into a shop and pay a fortune to have it done?i did see a post by slick "my 45 minute 3.4 dohc alternator repair" and i am wondering if that is the procedure i would have to go through to succeed in removing mine?please help...thanks in advance.

slick Posted March 19, 2007 Report Share Posted March 19, 2007 You should be able to test the output of the alternator with a multimeter. Quote Link to comment Share on other sites More sharing options...
1990lumina Posted March 19, 2007 Report Share Posted March 19, 2007 If the alternator is working properly you should have around 14.4volts of voltage on your multimeter, at full oad (rear defogger, full fan, all the lights on, etc).. If it's sitting around 12volts or less then it's not functioning properly, or at all. Quote Link to comment Share on other sites More sharing options...
SigEpCutlass Posted March 19, 2007 Report Share Posted March 19, 2007 If you find that the alternator needs replacement after testing it with a multimeter, refer to slick's writeup to save you some time replacing it.
