Alarm is going off. Oil level good. Doesn't seem to be running hot. Smoke out exhaust so seems to be getting oil. Any help please! Thank you
 
Disconnect the temp. switch Tan/blue wire and then the oil level switch...float may have sunk. If alarm turns off the switch is defective.
 
What colors are wires for oil switch?

The same circuit...tan/blue. The switch is on the bottom of my 115 HP tank...check there for yours. Disconnect the bullett connector for the temp first...if it turns off you found the culprit. If it still sounds try the oil tank. If removing both switches doesn't turn it off there is a short to ground in the circuit or the alarm is defective.

Determined it was oil tank. Pulled prob out that doesn't even touch oil and put it right back in. Now the buzzer. Is off. Don't really understand why but now it works perfectly.
