My car died, last couple of days the volt gauge has been slowly going less , today less than a half but drove ok , I checked battery and had 13- 14 volts on meter while gauge said less than half so I thought gauge was out as it did act up sometimes.Anyways driving home today gauge slowly went to 0 and died.Battery is ok and things wirk like radio , seat adjust etc, when turned on there is no cranking just a clicking, from one of 3 relays by airbox and I can feel it in EGR when I put my hand there believe it or not.I just did intake repair few weeks ago car has been great.Can an alternator do this,battery is brand new.and has 11 volts when I left it at a lot.Something electrical is screwy.Also I have been having my alarm set off once in a while when I open door even though it wasnt locked.When I push brake sometimes lights would flicker.Trying to be thorough, for a diagnosis.

Even a very dead battery can show 12 volts but not have enough power to start the engine. Charge the battery tonight. In the morning hook everything up & check the voltage of the battery. Then start the car & repeat check of the battery voltage. Should be higher with the engine running. If it isn't either the alt is bad or you have a bad connection somewhere.

What he said.
I'd like to add that my gauge acted like that, drooping under halfway (12V?)
I got a salvage yard alternator for $20 outright and I've had no problems since.

Okay thanks guys, I figure alt as battery is about 1 1/2 months old.Buddy is getting me an alt for free from a 89 bonn that I gave him we will see how that works.

The rectifier bridge is weak on our cars and burns out after 50k or so miles. Jc Whitney used to sell a cool pack kit with fins to keep the back half cool but I can't seem to find it anymore.

What is rectifier bridge.

edit- nevermind search is my friend , thanks

John that sucks-
Im not sure what a rectifier bridge is tho-

Thanks guys put in new alternator and boosted now she runs.

John
Good to hear that you got her going again. THe alternater went on mine a week ago- luckily I had a spare.

spare is good , Mike.
