My low oil light keeps coming on.The tank is full.How does a shade tree guy check the tank to see if it is a sensor tank problem or a wirring problem between the tank and my dash?the motor was off last week by a fiberglass shop but they claimed they put it all back together. TO BE FAIR to the fiberglass shop when I first got the boat back from the shop I took it out and the low oil light started coming on right away, I filled the oil tank on the motor and the light went off for the rest of the weekend until the last run back in the ramp .Now it stays on at all times.
