boobaru Posted November 24, 2004 Share Posted November 24, 2004 I have an 84 gl wagon and when I drive it the volts go way up when the rpms are high. if there is such a thing as a regulator could that be it? I also took out the alternator a few weeks ago and thought it could be the tension of the belt? anyone know what it could be? Quote Link to comment Share on other sites More sharing options...
NorthWet Posted November 24, 2004 Share Posted November 24, 2004 I was wrong before on which models had an external voltage regulator and which have an internal VR, but I believe that yours is an EA81 which should have an VR external to the alternator. Either way, yes, there is a VR that could go bad. Quote Link to comment Share on other sites More sharing options...

TROGDOR! Posted August 8, 2005 Share Posted August 8, 2005 EA81's after 1982?? I believe had an internal regulator, and used an alternator identical to an EA82. Just like Sweet82 said, your alternator is toast. Quote Link to comment Share on other sites More sharing options...
