FirstPriority Posted July 17, 2016 Report Share Posted July 17, 2016 I have a 2006 Pathy 2200v with a 200 vmax. I just noticed that on my past two trips my hour meter has not counted time. It seems to be the only thing not working. Any body with with any thoughts what I should check on? Link to comment Share on other sites More sharing options...
Bamaskeet Posted July 17, 2016 Report Share Posted July 17, 2016 The hour meter just counts time when your key is in the on position, not when your motor is running. I would check to make sure you have power going to it when your key is in the on position. Link to comment Share on other sites More sharing options...

FirstPriority Posted July 17, 2016 Author Report Share Posted July 17, 2016 Just to verify. If it didn't have power it wouldn't show any information correct? Are we we saying power to the gauge or the ignition switch? bit confused sorry... Link to comment Share on other sites More sharing options...
Bamaskeet Posted July 18, 2016 Report Share Posted July 18, 2016 Your hour meter reads when your ignition key is in the on position, whether your motor is running or not, so it's reading 12 volts off your ignition switch. Link to comment Share on other sites More sharing options...
NCTribute Posted July 18, 2016 Report Share Posted July 18, 2016 All the hour meters I have been involved with in construction equipment need the key switch in the on position and sense that the alternator is turning via the 'W' tap (frequency signal used for rpm). So they sense when the engine is in operation, not just a key switch position. What is the value of sensing a key switch position? Most people are using the hour meter for maintenance intervals, so again a key switch position is not the ideal indicator. I could very well be wrong on how outboards are set up, but does someone have more evidence of the operation? The only thing I could find on Yamaha hour meters was just a simple statement that they recorded engine operation hours. Link to comment Share on other sites More sharing options...
smilemaker Posted July 19, 2016 Report Share Posted July 19, 2016 there is a difference in heavy equipment hrs and outboard motor hrs. Heavy equipment is tied to rpm and the greater the rpm the faster the hr passes. Outboard motor hrs are a true time. If the gauge is on the clock is running. If you put the motor on the computer it will tell you how much time has been spent at what rpm. For boats that troll a lot they will have huge numbers at low rpm, Now if you can figure out how a computer calculates time for a download to occur all of this is easy. Does anyone have a schematic for the wire to the gauge. It may show which wire controls the hrs Link to comment Share on other sites More sharing options...
NCTribute Posted July 19, 2016 Report Share Posted July 19, 2016 An hour is an hour on heavy equipment, the alternator signal is just a trigger to make sure that only time while the engine is operating is shown, the actual rpm does not affect anything on the hour meter.

Bamaskeet Posted July 19, 2016 Report Share Posted July 19, 2016 The hour meter on a outboard just measures when the key is in the on position, it's just a clock. That's why the hour meter and the ECM hours often will not jive. If you have the key in the on position while working on something, your hour meter will be running while your engine might not be running. Its very common for the hour meter to read higher hours than the ECM. Link to comment Share on other sites More sharing options...
