Pegged means it goes to the maximum deflection. Gauges have a small "peg" there so the needle must stop and not make a complete circle and twist off. The oil level sender has a ground on one side and the other wire/side goes to the gauge. The sender is a variable resistor. that changes based on the movement of a float mounted on a lever arm floating in the oil. You can tell the side attached to ground by simply looking. An "open" will give you full needle deflection (pegged) and a short (to ground) should give no needle deflection. You can test the sender by disconnecting the output wire going to the gauge. That creates an "open" which gives full deflection. Touching that wire to chassis ground should give no needled deflection. If it works like described...the problem is either the sender or bad contacts on the ground wire side. If it does not, the problem is in the gauge or wiring between the sender and gauge.
