Hello Everyone!

Last year i bought an Ohlson 8.8 sailing boat with a volvo penta MD7A in it. The motor runs reasonably for its age with one problem.
The alarm sounds the moment you turn the key. It goes constantly in a spectrum between almost inaudible and ear ripping at seemingly random times. This is both annoying but also defeats the purpose of having an alarm, because i don't know if anything is wrong

I suspect that it might be the alarm separator number 17 on this list: https://www.volvopenta.com/shop/0/pa...tions/54146719
But that's discontinued. My question is, how do fix this? can i replace it with some other separator or is there another likely culprit? Would it be an idea to just buy a functioning instrument panel and are there any compatibility issues i should be mindful of?

Any help would be appreciated!

best regards
Kristoffer
