Hello All,

I was driving home from work when I got a "Low Battery Voltage" message. I took it to a parts store to test the alternator where they told me the battery was too dead to test the alternator. When we went to change the battery (I have never seen anything that's not a race car or boom car have the battery in the trunk), I had forgotten about some junk in there so I said I'd empty the trunk and come back. On my way home.. the RPMs died in mid drive. She was dead! I got a jump to try and make it home.. and I made it 80% of the rest of the journey before it died and I had to jump 2 more times to make it the remaining 20% home- also now getting the message "Immobilizer See Manual".

After speaking with the dealer and a few shops in town, I'm not prepared to pay what they're asking for the diagnosis and repair. I'm hoping someone here has gone through this and can help me better understand how intensive this job is. Am I looking at 4 hours of work or a whole weekend? Is this something I need special tools for or can I get by with an average man's tools set?

Thanks in advance for the help and guidance.

The regulator is most likely bad check out this post.

Thanks for your reply!

That post is helpful, lots of good info in there.

My question, however, is what do I need to do in order to confirm it is in fact the regulator and not the alternator? I just want to avoid buying the more expensive part or at least not buy the cheaper to find out the more expensive was really the issue.

 

It is hard to figure it out without replacing the regulator.
It is a 50/50 chance.
I have done about 100 regulators and only had 1 bad Alt.
