What is this warning symbol?

[Dr. D]

When my engine overheated, a few minutes after I turned the engine off there was another alarm. I forget how I silenced it. On the electrical control panel there appeared a symbol I haven't seen before, a "1" in a triangle. Anyone recognize it? I can't find it in the manuals I have.

I believe that indicates your engine battery is getting low ... I think it usually sounds when it goes below 12.7 v. Connect to shore power or run your engine (if your alternator is working properly) to recharge your engine battery. How old are your batteries? I was getting this alarm far too often and it turns out I just needed to install new batteries. Alarm hasn't sounded since. Good luck.

Urban_Guy is close I think. It is a battery voltage alarm, but triggered by either overvoltage (above 14.75), or under (11.0 main battery, 12.0 engine and aux batteries). See section 3.7 of the attached manual for the panel.

I don't believe in coincidences, was there a large load, like a refrigerator, present for some time after the engine was turned off?

David: Thanks so much for the manual! I did not get that with the set of documents with the boat.

Benny: No large load. I'm not sure what caused that. Once repairs are done I need to check that there was no damage to the electrical system; not likely, but a chance.
