Blown fuse alarm

We have been out on the boat for 1 month. Yesterday on a long run, I received this error: “Battery Monitor - Lynx Smart BMS HQ2443G94VC [0], Distributor A Fuse 2 Blown: Alarm”. 2 minutes later, it cleared. It did this 8 times, with varying lengths of time before it resolved.

I did not lose power while the alarm was active.

I’m on firmware 3.55.

I have seen this on 48V systems pulling high currents. There was a tech bulletin on this a couple of years ago. Please provide some more details on your system and the load connected to Fuse 2.

It turns out that the nut on this fuse was loose. Tightened it and the alarm is gone.
