Background. I bought the car in non-running condition. I am completing a full restoration and bringing her back to life. My car has build date of 4/11/69. The wiring harness has the black plug. Circuit board was red. At this point I don't know if prior owner would have changed harness or circuit board. I assumed the board so I bought the blue Elim/xr7 board. Here is my issue. As soon as I hook up the battery cables, the low fuel light comes on, even with the ignition off . Other than that, the rest seems okay. What is powering the low fuel light? It should only come on when the key is in the run position, right?
