Is the buzzer alarm and the warning red flashing dash light tied together? As in should they always work and come on together? Last weekend my red light flashed and my oil light came on. Stopped and had to add oil but everything good afterwards. Used machine every day a few hours til today my buzzer started going off but I have no warning lights anywhere on. My check button shows all lights should be working. Alarm sometimes almost stops and quiets like it is shorting but then can come back full blast. Oil pressure gauge doesn’t work but machine has oil, temp stays good always about 195-200.
