150 Black Max-Horn from shift control box

[JohnnyJ]

I recently started getting a continuous horn from the throttle/shift control box. Sometimes it will stop after a few minutes, and other times it stays on over an hour. Any suggestions would be appreciated. It is not the beep beep sound from the oil injection, it is a continulus warning horn

If it's legit, you're overheating. If not, the alarm wiring has a short to ground, the temp sensor is shorted, or the oil alarm module is bad.
