cooling fan runs when jumping ALDL
My 89 RS 2.8 V6. I am trying to get it running to evaluate its condition. My radiator cooling fan comes on when when I jump pins A & B on the diagnostics block. If this is not normal, where do I begin looking. Is mine one of those controlled by the ECM? (my ECM is 1227302)
