BRAVO 3 LOW LUBE ALARM

PickleRick

Have you looked for any loose wires/bad grounds?  Could cause random alarms despite all good sensors. I believe most connectors are bullet.

In VVM you can silence and block the alarms, have you tried that temporarily? I also think the low lube alarm is more persistent and is stored in freeze frame and may need the tool to clear fully.

yeah, it silences the alarm on the app, but in this case not at the helm.

I don't know if i would jump to a bad ECU off the bat. This feels more like a short or bad wire.  When you messed with the wires and the problem went away for a while.  That to me is a sign to dig further into those wires.  Something there is intermittent.  That could be a loose connection, corrosion or almost broken wire.  For a 23 yr old boat....that would be my guess.  If remember correctly the purple wire off the ignition is just 12v when the engine is on or in the aux position.  All of the wires behind the guages go to one large wireing harness that is then plugged into your main harness that runs to the engine.  Maybe follow the wires in the harness.  Unplug the two wiring harnesses and look for corrosion or anything broken or loose.

I believe blocking will also stop the beeps.
