I'm not sure yet. It's an ancient little box with alarm lights and a buzzer. It's always worked, but not this time.
I think I'll pull both the alarm temp sender and alarm oil sender. Maybe start from scratch with another system or put something together with individual alarms. Maybe just consider the exhaust alarm mentioned above for a temp alarm?
I like having them, I check the panel gauges regularly but that may not be enough in some instances.
