Hi, The display on my hour meter has stopped working, ie the display is blank. Has anyone else experienced this problem? Any suggestions on how to resolve it would be appreciated. Are there any tests I can do to ascertain if it's the panel or a cable problem? The boat is a 36i (2008) with Yanmar 3YM30. Many thanks Noel

Hi Noel, here is what was posted in another forum Re: Hour meter on SO 362 « Reply #10 on Apr 15, 2011, 10:35pm » -------------------------------------------------------------------------------- I have had a similar problem over the last two seasons on my SO35, yanmar instrument. Last weekend I stripped it out to try and find the problem. Discovered that the wiring harness just before the plug had at some point in the past overheated and the outer coating of the wire for the hour meter had slightly melted. It was not shorting but once I separated the cables (they were slightly stuck together) and applied a new coating of insulating tape plus cleaned the terminals I had the readings back on the meter. I am away again this weekend so I will know if the display remains visible(not much wind forecast so will have the engine running for 4-5 hours) Read more: jeanneau.proboards.com/index.cgi?action=display&board=general&thread=1098&page=1#ixzz1T3yeNy3d

Hi Flightdeck, Thanks for the link, I'll follow up this week and check out the various suggestions.
Instrumentation is not my strong point so forgive what may be a stupid question, does the hour meter work simply by being connected to the 12v when the engine (switch) is on or is there an input from the engine or altenator.
Many thanks Noel

Noel,
Do not quote me on your boat or setup. Nor do I have an hr meter on my boat, my bobcat and mini trackhoe on the other hand do have hr meters, they see to work based on the key being on. Some do work on rpms. These it is possible to get an hr plus or minus in an actual hrs useage. As the meter will use say 2500 rpms as an hours use. If you motor at 2000, it will take a bit more than an hour to get an hours use, ie about .8 hrs of use per actual hour. If you motor at 3000 rpms, then the meter will register about 1.25 hrs per hr of actual use. Please note, my math may be off, as I have not used a calculator to figure out the difference. but hopefully the examples show the what and how it will happen.
