Customer Question

What could be wrong with my two 2005 waverunners. When is a VX 1100 sport and the other is an FX cruiser we are both do not display the miles per hour but they do display the check on water readings. In both cases the speedometer we'll under the hull spin freely

Hi and thank you for your question.

It is quite curious that both wave runners have the same problem, no speedo display. You said they go through the check, which is encouraging, but do the other functions actually work after it goes through the check? Things such as the tachometer, fuel level gauge, hour meter, etc?

If the paddle wheels are spinning freely and you are still not getting any display while riding the skis, I would suggest looking for the triangular white plastic connector and see if it is unplugged or possibly corroded.

Let me know what you find with this and we can go from here if need be.

Where would I find the triangular white connector. Any chance you could give me some type of direction to find it
Expert:  RSRBOB replied 1 year ago.

Typically it is found on the left side of the craft just ahead of the engine compartment. You should see the main harness of wires there and it should be in that bunch. Alternatively, you can start at the leads coming out of the meter and trace them backwards to the white triangular connector. It should not be terribly difficult to find. You can try pulling the seat off and looking from inside the engine compartment forward or open the front hatch and pull the storage locker out and look back towards the engine.

Ok thanks. If the wire and connector look good what are the next rule outs

Powering up the hall effect sensors and testing the output.

What do you mean by powering up the "hall"
Expert:  RSRBOB replied 1 year ago.

Its a test for the speed sensor. I am still waiting for you to answer the other questions before we get into that. It is important that we proceed in a methodical order. Please refer to my first response and address those questions and inspections and let me know what you find. Truly, the hall effect failing is very low probability so I suspect it is something else.

I will look at the triangular plug this weekend I am not at home at this time to answer your question
Expert:  RSRBOB replied 1 year ago.

Not a problem. I completely understand. I am going with the highest probability of failure first. Hall effect sensors just don't ever fail. Well, almost never. :)

OK I'm done for this question thank you I'll figure it out
