alright. i ran a wire from a terminal on the fuse box that only gets power with the switch on to the #4 terminal on the regulator(the one reading out to 5.4v before) with that wire in, i get the 12v on the wire there, and since the generator light is getting it's 12v from the other side, it goes out like it's supposed to when the engine starts running. i still only get 12.5v at the terminals on the back of the alternator, so i'm going to go have it checked out. now, if that light is grounded somewhere it shouldn't be, can i leave the #4 terminal hooked up the way it is and still have my battery charge? (since the light is obviously getting the 12v from both sides like it should be).
