I have a 2012 150 hp, E150DPXINE, that has less than 200 hours.  The problem I have is with the gauges.  When the motor has not been used and is cold, the tach and speedometer both work fine.  They go through the self check and operate fine.

When I stop and turn the engine off, then return and start the engine (when warm) the tach does not come on.  No self check and no operation.  The speedometer comes on and goes through self check , then remains on but does not indicate speed.

The other gauges, trim indicator and battery charging both work at all times.

Any ideas on what's causing this?

A more specific identification of the instruments would be helpful.  ICON is a very loosely used word.

Thanks for the quick reply.  I am not sure what info you might need.  They are the ICON Pro Series Gauges as labeled on the user guide.  The software is PGFS 45F Rev B1     2/13/2012.

Tachometer is the "master" instrument and speedometer is the "slave".  If tach is not fully functional (and based upon your description, it is not) then the speedo should not be expected to function.

Verify that the source of switched D.C. for powering the tach is present when the tach does not power up as evidenced by no self check, etc.  If power is present, then I would suspect a defective tachometer.  Likely not related to the engine being heated up but rather by the tachometer being heated up.

Thanks for the help.  Not being an electrical mechanic or really any kind of reasonable mechanic it would seem that the best place to check the power is with the plug going into the tach.  Remove the plug and check the purple and black leads ???  Your help is really appreciated!

Purple would be the Key On power.  Black will be the Ground.  Bad connections or wiring on either side could also cause problems - including the plug itself.

As ElderSparky says, if that's all OK, then substituting a known good tach would tell the tale.  You could just buy a new tach and while installing it (unknowingly) correct a bad connection.  Hmmm, must have been a bad gauge then.  [wink]  It does sound suspicious that it could be the tach warming up and failing though.

Let us know how it goes.

Thanks to all for help.  I did find power  thru the plug and tach still didn't work.  sounds like a new tach.

If you are confident the ICON Pro RPM gauge is receiving good, clean power AND there is no response from the gauge, then the gauge may be bad. But before making that inference from you measurement of voltage at the multi-pin connector for the gauge, you must verify that fhere really is POWER available there. A sensitive Voltmeter will indicate 12-Volts even if there are hundreds or thousands of Ohms resistance in the power wiring due to a poor connection upstream in either the positive or negative circuit.

You should also test for the effect of temperature on the ICON Pro RPM gauge. See if there is a correlation between the gauge getting warm and the gauge not working. If the gauge is exposed to strong tropical sunlight, it might get very warm. Remember—it was designed in Wisconsin where a day time temperature of 65-degrees-F means mid-summer.

I appreciate the follow up.  I did get a good volt reading at the plug so I felt there was good power to the tach.  Not being a good electrical mechanic, I did however try to get an OHM reading between the positive and negative poles on the plug.  I got no OHM reading.  Was that correct method or just luck on my part.  

I am located way up in New York State so I don't think the weather/temperature had a great effect.  This started last fall and continued to date.  Thanks again for your help.

Just checking the gauge again and realized when power is on and to the tach, the tach did not work however the speedo would go thru the self test completely so it is getting power form the tach.  I would think if the power were bad that might not happen.  Any thoughts or ideas for further testing?

It is sounding like the tach - able to pass power, but not function correctly itself?

You did say at first though that it was "after warming up", and I'm thinking it's cold now - still won't work?  Any person/dealer nearby with a known good gauge to "borrow and try"?  That will narrow things down to either wiring or gauge.  Then you can concentrate your efforts more precisely.

The ICOM Pro Speedometer gauge getting power indicates the power to the RPM gauge is good. That indicates a problem in the RPM gauge.

I am looking at getting a new tach gauge.  The question now is...There have been a number of ICON Pro  tachs with new product numbers that have replaced the old one of mine.  The question becomes do the new ones have a different firmware and or software to make the old speedo incompatible with the new tach?  Does that mean I have to buy a new speedo to go with the new tach?  I haven't been able to get to get an answer to that as yet.

If anybody has replaced an old tach with a current one I would like to understand any difficulty with installation and operation of the old speedo.  Thanks

my tach was bad, replaced under warranty, however the speedo was not compatable. BRP replaced both gauges no charge.  Gauges were installed in June of 2016 and replaced in June of 2018.

I appreciate the info.  I did order a new tach so your info sounds like bad news. I will publish my findings when the new tach arrives, but it sounds like it won't be compatible.  Thanks again.
