    Possible Tachometer Fix

    I'm investigating a possible DIY fix for the intermittently working tach.

    I need one or two instrument clusters that exhibit the intermittently working tach.

    In return you will get back your instrument cluster hopefully with a working tach.

    Thanks Guys!

    Mine had that issue when I bought it and we just fixed a connection right up against the tach.

    It is a loose connection that is causing the problem.
    Mine has been doing it for years...
    I need a little time to fix it.

    Was anyone able to zero in on the solution to this? I would be interested in a diy write-up, my newly acquired manual swap marauder is exhibiting the intermittent tach issues and I want to ensure I don't miss shifts. I have some decent soldering skills I can put to work
