I've been messing with electronics lately. The modules have all been removed from the tail and going behind the ram air tubes. I just noticed today that the tach and speedo are sitting both at the 2 o'clock position. I did turn the key on a time or two with the tip over sensor disconnected and got the FI ERROR message on the multimeter. I suppose that is all it is and when I turn the key on it will go back to 0?
