Hi everyone

My warning horn in the control box has a low volume constant alarm even before the engine has started, also the RPM gauge has stopped working?

I have checked the oil and temp sensors/warning horn and they work fine, my fish finder turned itself off a couple off times also?

the only thing I have done to it since last use (3 weeks ago) is change the fuel filter but I doubt this is related.

any help would be greatly appreciated as I'm losing sleep over this!!!

The low voltage horn sounds a like a bad oil module have you disconnected it, to see if the horn stops? The gauges sound like a bad ground.
