    Tachometer Needle Question

    hey guys quick question.

    im sending my si board for refurb at bav rest and as i was taking the cluster apart i noticed that all the function needles return to their starting positions when you move them except for my tac, if i move the needle to 1k it stays there, i find certain spots between 1 and 7 where it will return a little and then stop again.

    I have not had the speedo working since I've owned it and the si board didn't even have its led board on it...

    Just want to make sure i shouldn't be sending my whole cluster in to be looked at and pay the extra or does the tac run differently than the rest of the gages.

    thanks in advance and Merry Christmas.

    Sounds like a bad tach or the needle was hyperextended by previous owner. That is not normal, replace tach.
