rebuilder; You may be right on your bet. As I know it, the light_beeper sender is a switch that breaks the ground from the wire to the block when a predetermined pressure is reached, cancelling the warning light, and silencing the beeper. If this same wire were grounded anywhere else along the line, it would also cause an alarm condition. If you were to take off the pressure gauge wire and attach it to the light_beeper sender instead, and the pressure gauge pegs to the high side and stays there with engine running, then the light_beeper sender is at fault because of a constant ground condition. If the pressure gauge shows zero, then there is a ground along the light_beeper wire somewhere. Be sure to have light_beeper wire disconnected from the post of the sender when this is done, so as to eliminate a false reading on the pressure gauge. Good luck........
