HEY I HAVE A LITTLE PROBLEM WITH MY HOOD TACH. I'M PRETTY SURE THAT THE TACH IS THE PROBLEM AND NOT THE WIRES; THE TACH WILL STAY ON ZERO UNTIL I REV THE ENGING THEN IT SLOWLY MOVE UNTIL IT IS PIN AT 9 RPM THEN IT STARTS TO WORK BACKWARDS. WHEN THE ENGINE IS OFF IT NOW STAYS ON THE 9RPM. CAN IT BE FIX OR DO I HAVE TO BUY ANOTHER. IT IS SEALED UNIT.
