Alternator warm with key out
I have a new internally regulated alternator that I wired up for my 68 coupe using the plug-in adaptor (that goes in the stock connection for the voltage regulator). Problem is, when key is out and nothing is on, the alternator is warm. I assume this isn't correct and I will probably end up with a dead battery....or something worse. All other electrical is working fine. I did a search and found some related posts but nothing on point...except for one posting that said get a new alternator. If, hypothetically, I assume that the alternator is okay, does anyone know if there might be something related to the wiring that I might check out? There are the 3 wires to the alternator........blue/white and red. Seems hard to mess that up, but you never know!
