Having problems with the unforgiving charging system in my 66' Malibu. Everything from the coil to the battery is brand new. Basically everything electrical is brand new. Start the car with first alternator, everythings fine but gen light is on, run it a round for a while light does'nt go off with lights and everything on. Put the the multi meter on the battery,shows 9.4 volts same on the lead wire on alternator, horn relay same thing. Red wire on voltage regulator same thing. This all with engine running above idle. Promptly remove alternator gave it back to Auto Zone tell them to give me another one. Put it on seems to put out around 13.8 volts. But still have the gen light on. Measured blue wire reads 6.5 volts, white wire 2.3 volts same at regulator.Quit for the night checked it again the next day,after jumping the battery and again reading around 9.something volts. What the hell? The brand new borg warner select regulator is grounded properly. belt is tight,battery has been tested and is just fine. Can't really run it around town yet,not legal. Have to jump it everytime to start it. Unless I take the battery to O'reilly's to get it charged, I have to jump it to start it if I have been running it for testing. Is the remanufactured duralast alternator from Auto Zone just a lump of crap or what? Or is something killing it. Should I take it to pro or what?
