SSThunder Posted April 21, 2008 Report Share Posted April 21, 2008 I noticed my volts were down for weeks so during my last oil chage they checked that and told me I need a new battery. I knew that already so I replaced it myself yesterday. Today my volts are down again on idle. I'm just wondering if my alternator is going bad or maybe my belt is slipping. What do you guys think? I've got over 76K miles on the ss. I'll probably order a new belt tomorrow since it's good to have a backup. Quote Link to comment Share on other sites More sharing options...

Fireman31 Posted April 21, 2008 Report Share Posted April 21, 2008 I would figure it's a bad alternator.....did you pin the crank yet jeremy? Quote Link to comment Share on other sites More sharing options...
brobradh77 Posted April 21, 2008 Report Share Posted April 21, 2008 My guess is the altenator as well. Quote Link to comment Share on other sites More sharing options...

SSThunder Posted April 22, 2008 Author Report Share Posted April 22, 2008 Is there a way I can test the alternator? Quote Link to comment Share on other sites More sharing options...
brobradh77 Posted April 22, 2008 Report Share Posted April 22, 2008 should be able to take it to a place like AutoZone and they can tst it for you...or maybe start your truck unhook the battery and see if it runs ok???????????? Quote Link to comment Share on other sites More sharing options...
desrtrat Posted April 22, 2008 Report Share Posted April 22, 2008 Is there a way I can test the alternator? take a volt meter and check on voltage out put at the battery. should be 14-14.5 volts. you can also check on the back of your alt. your positive connection should be just a little higher than what you get at the battery, maybe about .3 volts more. if your only getting about 13 volts or less, then check your cable ends for corrosion, clean as necessary. if no change, your voltage regulator is going bad time to replace.. if you decide to take the truck to a place to have it checked when the truck is running, have them also do a load test on your battery.. good luck Quote Link to comment Share on other sites More sharing options...
