To all. Thank you for all the advice, my daughter has been careful cleaning all connections she could find with a toothbrush and WD40 and the problem has now been cleared. GIRL POWER she told me!

There is some damp in the multiplug, she is letting it dry out. The alarms stopped when is was disconnected.

My daughter is checking the switch and the multiplug tomorrow.

That is very helpful, the boat is 30 years old and the engine is around 15 so corrosion of the multiplug could be an issue.

will check the multiplug as easy and is basics so a good starting point.

Yes there seems to be starting a consensus on the switch. Thanks

What you say makes plenty of sense and I will check the multiplug and the ignition switch as best I can. The alarms still sound when the engine is running.

How do I check if a sender is faulty? Can I put on ohmmeter between the sender connection and earth and check for a reading?

The alarms started after I worked on the pump. The pump was not electrically disconnected The instrument panel was not removed before the alarms sounded, but I had a quick check behind after the fault to check it looked alright. The pump is in the front of the cabin next to the water tank. A short could be the issue but have not fully checked the switch out. The boat electrics are totally isolated and the boat is at peace.

It has an ignition key and it is off and removed

Thanks for the help.

This has only just started Yes on a leaking water pump. Seals changed. That is always possible It is all engine alarms and lights only. I am currently away from the boat and it does have a ignition switch.

How do I reply to folks answers to my question?

I have a Beta 43 and the alarms and warning lights are continually sounding and lit when the ingnition is off and the engine not running, any ideas hiw to cure the problem. Thank you.
