Customer Question

I have a 2003 135 hp Optimax ser # ***** Recently a Smartcraft (ver 3.04) gauge and CAN harness (Part # *****) were added. The correct end of the CAn is pluged into the motor. The Smartcraft gauge, upon sratrting the motor, announces the bell, engine and oil pressure icons, then 4 beeps every 2 minutes.
If I unplug the CAN harness at the motor everything appears normal.
Bad harness?
Bad gauge?
Wrong software version?

Hello, my name is***** you for allowing me to assist you today.
Go into the calibration of the gauges, make sure that the fuel, oil, and water tanks are not turned on. If they are on you will get this alarm, turn them all to off if you do not have these sensors installed.
