Merc 5.0L ign. on signal
 

Just bought a Sea Ray w/ twin 5.0L I/O's (PCM-555). When you energize the ignition it's supposed to sound a single 1-2 sec. chirp to indicate all is good. More than 1/2 the time one eng. when energized will start a non-stop rapid chirping. If you start it, the chirping stops and it runs normally. The SmartCraft gauges indicate no issues. I scanned it with a Rinda and there are no fault codes except one for a Pitot pressure sensor issue (#92). I can't find anything in the SmartCraft booklet or the service manual that describes this condition. Anyone ever experienced this?
