loyale1993 Posted May 16, 2016 Share Posted May 16, 2016 All of my warning indicators (Battery, AT oil temp, Parking brake, no CEL) came on. At first they were very dim and flickering but then fully lit after a couple minutes. Also, the other day I go to start my car after driving at highway speeds for 20 minutes and my battery was dead. I tested my alternator and it is putting out 14 volts and my battery is accepting the charge and has been fine for the last 4 or 5 days. Any ideas on what this could mean?

rdweninger Posted May 16, 2016 Share Posted May 16, 2016 Really sounds like a bad alternator. You said you tested it, but maybe have a shop bench test it. Quote Link to comment Share on other sites More sharing options...
DaveT Posted May 16, 2016 Share Posted May 16, 2016 Sounds like alternator dieing. It might be intermittent. My experience with more than a few is that original ea82 alternators get to around 150,000 miles and one of the brushes wears out. Other things also, but that one is like clockwork. Would not hurt to check the connections from the main out to the fusible link box and battery also. Quote Link to comment Share on other sites More sharing options...
loyale1993 Posted May 16, 2016 Author Share Posted May 16, 2016 Ok, I will have it bench tested. It is the original and the car has around 170k so I'm sure it's time for a replacement. I originally took it to be bench tested but the parts store I went to didn't have the right harness for this alternator. They did test the battery and said the load amps checked out but the volts were a little low. Thanks for your help fellas Quote Link to comment Share on other sites More sharing options...
l75eya Posted May 16, 2016 Share Posted May 16, 2016 Testing with a multimeter doesn't do much. It needs to be load tested. All the lamps illuminating is pretty much all the testing you need though, it's time for a replacement. Quote Link to comment Share on other sites More sharing options...

loyale1993 Posted May 22, 2016 Author Share Posted May 22, 2016 Update: Over my weekend I opened the hood to take the alternator out and found that the belt was very loose. Apparently I didn't tighten the bolt down enough. Anyway, I removed the alternator and took it in to be bench tested and it passed. So I guess everything is fine for now. I still can't explain why my car battery randomly died after driving the car and it seems to be fine now? Gremlins I guess. Anyway thought ya'll would like to know.

Anymore I always disconnect my batt even if I'm replacing my wiper blades JUST FOR THE HELL OF IT! LOL! 1 Quote Link to comment Share on other sites More sharing options...
