    Default Mx83 speedo sender

    Howdy happy people
    just wondering if anyone can confirm that the MX83 speedo sender operates on 5V and not 12v, did a search but couldnt find anything.
    Just hoping that i dont have to go grime surfing again and swap it over.
    thanks

    MZ12 Soarer which looks the same as MX83 grande is 12V...

    Then again I'm pretty sure that the dash has a diode and its own internal pull up so it doesn't really matter...

    edit- its in a ra23 w58/1g running off a home made loom and a speeco spedo

    I wired it up and couldnt get a pulse, so had a chat to my mate with a soarer and apparantly they run all 5v in the dash,so forth, which got me a bit worried.....

    Have you tried removing it and turning it over by hand slowly to check you get a pulse out?

    That would be where I'd start...

    One pin is earth , one is +12v , the other is output. Make sure you have it earthed properly.
