Bongo Fury

I have had a look on the search about my problem but just can't seen to find and item. My coolant alarm was buzzing on start up with no problems, but today has stopped buzzing and lighting up on start up. I have read about screws etc is this the same fault, or is there a fuse maybe?
kind regards

If the on start test isn't working then that suggests a problem with the power, as it can get its power from wherever the installer choose only you can check that out!m

Thanks, will check out later as i have been fiddling around that area last week.

Found some wire hanging down, push back up and bingo or Bongo the alarms buzzes now on start up another barri quirk.
