smashedz28 Posted February 25, 2011 Report Share Posted February 25, 2011 hmm. I have a 1997 Tahoe which i replaced the alternator on with a DB Electric 220A alternator... ever since i did that my idle voltage is crap (according to stock gauge) when i give it some rpm's its back up where it should be.. I dont see anything about my year vehicle. this whole time i thought i just bought a bunk alternator, i still think that. Mine just goes up and down with the RPM's, does this have anything to do with my vehicle or did I infact buy a garbage alternator lol.? Link to comment Share on other sites More sharing options...

Could be that your pulley is just too big on the alt so that when it idles it doesn't idle as high. Buying a smaller pulley would fix that problem. 2012 Civic Si Coupe - Nada lol Youtube Link to comment Share on other sites More sharing options...
