    Default Diagnosing HG holden speedo not working

    speedo stopped working in my kingswood the other day, done a bit of research and found a few possible answers which could be the cause but not sure how to go about diagnosing it.

    Just want to know the steps of finding the cause or how i can test it before i go out and buy a new speedo cable or open up the gearbox. Cars a 186/trimatic

    1st step
    undo cable from box .. and spin INNER cable by hand
    does dash needle move?
    if yes, possibly speedo gear/driven gear in box
    if not, remove cable from speedo head and insert small
    (maybe jewellers) screwdriver and spin... does needle move?
    yes = cable is stuffed
    no = speedo head is stuff so take it to Auto instrument guy

    HI
    Pull speedo and go for drive if cable end spins in dash ,speedo is your issue .


    Either way it would be a great idea to pull the inner cable out and light oil lube ,last longer and help prevent sticking
