    Hello friends,
    i have a trouble with the voltage and the fuel pressure gauges.
    The first don,t works ,it has three conections, two positives and a ground.Only the ground and one positive are connected to the printed circuit of the board.If i connect the other positive to the battery, the gauge goes to the maximun,18V.I don,t understand.The ground and the positive connection in the "run "key postion are goods.But only two of three are connected(???)
    The oil-pressure gauge neither works.If i disonnect the oil sender wire,the gauge goes to the maximun,if i connect this wire to ground goes to the minimal.
    Somebody can help me?If somebody has the gauges wire diagram and can send it to me ,i,ll thanks to him.Jorge.
