I have a 1990 mercury 175 HP black max and my low oil beeper continues to beep even though it has oil in both reservoirs. I changed the cap on the reservoir over the motor last year. The float on the cap appears to work properly.....I have disconnected the wires from the cap and it still beeps....I know that inside the cap is a reostat....Does anyone know how this works?
