Was driving home from work today and a service charging system. Warning came on my dash... i then watched as my colts droped .1 at a time then stalled out on the couch side of the road which is where a am now. What all should i be checking besides the altanator?... i REALLY am beginning to hate this car

Well the other possibilities are the cables, terminals, and battery. But that sounds like a bad alternator.

Depends what you pay for the part, and what the shop charges to put it in. Pretty large price range.

I watched plenty YouTube videos on changing alternator in our Devilles... One guy actually did it without removing the Radiator. Not recommended tho.

http://www.youtube.com/watch?v=an3rl8H0y0o (alternator out the bottom) Not recommended tho.


If i understood how to do it... U can do this yourself... Will take roughly an hour or two or 3.

Buy an alternator like Basscatt said and spend some quality time with your Deville. :D

Sorry for the multiple post but jus incase u want to try to do it yourself before considering the junk yard, ive posted the DIY instructions below...

GOOD LUCK

One source says standard labor hours for this job = 2.4, not counting any diagnostic time to first conclude it is a bad alternator.

Well at one point I didn't either but I'm learning as I go

Only thing I could suggest is find a mechanic that will Work With U -- Not Jus For U -- and will work with u for a reasonable wage

I would have posted pics and images but the CF won't accept the ones I have bc of their size

I've learned a lot from CF members but Google, YouTube and my Mechanic friend have been my best sources on understanding the Nortorious Northstar. :D

At least u can use the instructions I posted as a step by step reference. They're from the Service Manual.

This is why posting long, complicated procedures from the FSM is a waste of time in most cases.

All the steps are NOT there. That's why after most steps it says "Refer to xxxxx". You have to skip around the FSM.

mhswres1, if you're going to do this yourself, you're going to need a Helm FSM for your year and model. You can find them on Ebay.
