My boat has the Volvo MD-2030D diesel, and the standard control panel with a combo tach / engine-hour meter. The hour meter is intermittent - it registers the hours OK, but cannot always be read, because the display is "off". Usually, cycling the engine power switch will bring the display back to life, but even that is not working as well now.
I'm guessing the contacts have become oxidized / contaminated, but haven't figured out how to clean them. Any ideas?
