I took the relay from the other Datsun, and it will not work either; on this one. Pulling the light switch out, it only is supposed to control the low beam. Just turns on two of the four headlights. You activate the high beam; (the other two lights, making a total of four,) with the switch that is on the steering column. I am hoping that switch is not the problem. It is hardly ever used; so seems odd it would all of a sudden short out. The wiring is so messed up on this thing, that I almost suspect there is wiring that is shorted coming from that switch, if I can find it. Somewhere along the line, someone added extra wires to the wires that go to the relay, even. Wonder if that was done, to activate the lights with the alarm. I certainly do not know. There was once an alarm system in the vehicle, but I don't know if those wires added were part of the alarm system or not. Yes; it is the turn signal stalk that activates the high beams. Pull the switch on the dash; and you get the high beams and cannot turn them off when you move the turn signal stalk now, and that is not right. Should just be two lights coming on; not all four. Guess I just never noticed how much current when using high beams. Rarely use it in that position. I appreciate your input. So does that make sense? That it is a short on that switch (or wiring coming from it) controlled by that turn signal stalk? I am curious as to why someone added two wires to the wires already going to the relay. Maybe they are shorted somewhere. I can pull them, and check for continuity or voltage. She had driven the other one all winter, and just started driving this one a few weeks ago, and then all of sudden this problem. She says she has been turning on the lights and no problems. Until now. If you have any more thoughts or suggestions, please give them to me. I have never heard of such a thing before. I am going to go back out there and see what or where those extra wires go. Maybe those wires are activating the relay, and keeping the extra lights on. They are soldered onto the original wiring, and it definitely was not done at the factory, you can tell that! Thanks again for your input. I appreciate any ideas or thoughts. I went out there, and cut the extra wires to the relay. No difference. Will take the pieces off the column and see if I can see which wires go to the high beam switch, and go from there. I think that is what you were suggesting.
