    A couple of days ago I noticed a warning tone and the lights on the systems monitor panel as seen below. The engines hadn't been run for a few days and the bilge pump works just fine. I eneded up disconnecting the connector at the back of the panel just to silence the warning tone.

    Thoughts on what may be causing this? I am going to clean the connectors to see if it's just corrosion. 20200730_202345.jpg

    Thats a good one...A couple Questions

    1) Can you start the engines and generator?
    2) Do you have a halon suppression system installed??

    I'm not overly familiar with your model/year, but several of those systems would go through the Sea Fire control box. The odd duck is the forward bilge pump...

    This is the Systems Monitor electrical for a 1996 330. Not sure, but probably pretty close. I marked what has been activated, but can't find the associated drawing to see what these have in common.

    I would start by going back in the engine room and look for the systems monitor module connection box. Its usually a black box on the firewall with a bunch of wires coming into it., and look for blue, tan, white, brown and black wires. See if these is anything amiss. If you have a volt meter see if you have 12V on those terminal. I believe that 12V will activate the circuit.

    Its not made any longer and not a serviceable item so, fingers crossed it’s just the connection.
