Total Electronic Meltdown
#1
![Default](/forum/images/icons/icon1.gif)
Good morning everyone,
Interesting morning today for me. Got into my lovely 95 VDP this morning (she has been a total peach up til today) started her up, runs fine, then my battery light comes on. I check the leads, nothing is loose so i continue on my way. Further down the road, I roll down my window and sunroof, they are moving agonizingly slow. a few moments later, my cabin lights illuminate. Finally as i'm pulling into my office my transmission light and abs light comes on. Turned off the car and tried to start it again, and now it wont even turn over.
What the heck is happening? Do I have a bad battery and the low voltage is awakening the "electrical gremlins"?
The car ran and shifted fine, so im assuming all that is need is a new battery. Never had any electrical or battery issues before until today.
Also, I live in Florida and my jag hates cold weather. It's one of the coldest days of the year here today (low 40's F). Could the temperature come into play?
Give me help here guys!!!

What was the voltmeter doing during all of this?
Anyway, you gotta start somewhere so have the battery charged and load-tested and then, if needed, have the alternator output checked.
Move on to more esoteric possibilities and fixes only if those two steps don't reveal a problem

I read your symptoms the same way. It sounds as though your battery is not being properly charged and the alternator is not providing enough juice to run the car. Most local auto parts stores will do a basic check of your electrical system for free.
Cheers,
Don

Well, first of all, this is NOT something so dramatic that it should be labelled a "Meltdown". You just described a classic loss of voltage while driving. And you may well have ruined the battery when you fully discharged it. But you described no symptoms that point to a bad battery. The car started, then progressively lost systems that are sensitive to voltage.
Change the battery if you want to, but this car is not charging for what ever reason. And a new battery will drive it for hours until it discharges.

Anyways,
After running voltage tests at my mate's garage. We've all come to the conclusion that it is indeed a bad alternator.
Thank you for all for the help, gents. This forum is a beautiful thing!
