egowing Posted November 22, 2011 Share Posted November 22, 2011 1983 GL wagon with 1981 Brat 1800cc motor. Alternator has been rebuilt.....tests out great. BUT......I don't show charge until rpms are >3500! Then it shows charge at any rpm. Tests at the battery confirm no charge until this engine speed. All alternator and battery connections cleaned and tight. Fusable links new! What am I missing? email me: egowing@tds.net Ed Link to comment Share on other sites More sharing options...

gadberry Posted November 23, 2011 Share Posted November 23, 2011 What year is the alternator? 1981 had an external regulator and later models (most likely 1983) went to internal regulators withinh the alt.. I'm sorry that I can't recall the exact year for the change, and therefore, I prolly should keep my mouth shut... Double check your battery ground to the engine and fender FIRST!! That was my problem last year but it was the last item I replaced.. . It's in the archive somewheres too. Good luck Link to comment Share on other sites More sharing options...
