2 beeps and high RPM

jtray

I'm getting a 2 beep alert every couple of minutes and my RPM's were sitting around 6500 on the gauge.  The engine sounds solid.  Any input?

I apologize.  I should state its a 2004 Rinker 232 5.0

2 beeps each minute could be any number of sensors. Best to get plugged in to look at the code.

Tachometers from that era are notorious for problems such as sticking.  Try tapping the tach with your hand.  It will probably go back down.  Another thing to try is unplugging and replugging the plugs on the back of the tach, or flipping the dip switches a few times.  

For the 2 beeps once per minute, it generally means a sensor is faulty (shorted or disconnected).  Look around for damaged or unplugged wires.  An engine scanner would tell you exactly where to look.  

Here's a list of alarm codes.
