It's a 01 DONZI 38zx with twin 500efi the port side motor alarm is going off after the motor starts and is running for 5 sec about. It stays on constantly. Gauges all look in the normal for charging, water temp, oil pressure, oil temp, and my raw water pump is flowing good when I look at the sea strainer. Is there a way to find out what this alarm maybe?(such as a constant alarm could be only small list of things) Or could it be anything down to a basic sensor on the motor?(check engine light alarm) I.e such as a intake pressure sensor, misfire, and so on. Thanks I'm upnorth trying to pinpoint this

There are only a couple of things that can trigger a constant, overheat, oil pressure low, or low drive fluid level. If the drive lube is full, unplug the wires to the bottle and see if it stops. Then unplug the single wire temp sender in the thermostat area. Then unplug the small switch down by the oil filter adapter, one of those should make the alarm go off.

my money is the drive fluid is low.

drive fluid reservoir.
