I've had my 2003 Nissan 70TLDI for a few months now and it has recently started giving me problems with the alarm going off. I have a tach with lights for oil, temp, and battery which all flash once on start up then stay off while running. The alarm starts beeping within a couple minutes after I start the motor and will not stop. It's not a constant beeeeeeeeep... but just beep beep beep beep....etc I have a 1000 cranking amp battery fully charged, plenty of injection oil and the motor is pissing great. What could this be from? When I originally started using the motor I noticed that if I left the key in the on position while the motor is off for more than about 5 minutes the alarm would make the same beeping, could this be related? Thanks in advance for any help.
