    I bought a Parts Place dash tachometer about 5 years ago for my 72 Skylark. Ever since i got it, when starting the car it would always max when cranking the engine but would perform well once engine started. Over this last season it got temperamental.... it would sometimes work or not or get stuck at at certain rpms.... now it just doesn't do anything.

    I haven't traced the wires yet but if it's the tach, does anyone fix these or am i stuck buying another one?

    I think i saw years ago there was a green wire i was suppose to snip for the tach and believe i did that but if someone can refresh me on that as well it would be appreciated.

    Not sure but i think mine is an older after market unit. wasn't working, took it apart and fixed loose solder joints. Pulled old solder and applied new, all is working. If your patient and have some soldering skills it's not that hard. Good luck.

    John has repaired a number of original and aftermarket tachs and clocks for us over the years. Nice guy and usually a pretty quick turnaround.

    Pulling dash is pretty easy. The hard part is pulling cluster forward enough to get tach removed. It really wasn't that bad though. Couple hours and its back together and working again, hopefully. Good luck.

    Yeah, i've done it a 30 times before on these cars.... i usually drop the column a bit which helps. Tbanks

    sriley531 Buckle up, this could get rough....

    I'll be interested to hear how the repair turns out. I have not one but 2 repro buick dash tachs that don't read accurately. Would love to get them repaired and sell them to recoup some funds. But the repair may make that cost prohibitive. As of now they're shelf fodder....

    I drop the column completely. Much easier access to the back of the cluster that way. I also place a towel over the column so that when I manipulate the cluster I don’t scratch the column.

    You can try sneaking it out thru the radio opening

    And if you drop the column, don’t forget to first unscrew the small hook for the shift indicator on floor shift cars.
