i just did my serpentine setup on my 80 monte carlo and now my cars alt doesnt charge correctly. I purchased the harnes DELCO8078 and now it charges worst then ever.First off let me give you some details about the car
Its a 80 Mc that i swap the dash cluster to one with the gauges and Tach from a 87 MC SS and electric fan from a 2000 intrepid and had everything working correctly chargeing at about 13.5 volts with all on. Now i swap out the drive assembly and installed a serp setup from a 92 Caprice with a 105amp Alt also i installed a DELCO 8078 SI to CS harness for the proper chargeing. But now with everything on it drops down to about 8volts on the factory gauge. Also the 8078 harnes only has one resistor on the yellow wire and not the red as the pic i found on that harness has one on both lines i posted pics of the website pic i found for part #DELCO 8078 and the one i bought from Napa
