the tachs that are not serviceable have their circuitry completely coverd in a reddish-colored conformal coating. the ones that are havea small circuit board on the back that all the small componets can be seen on.
I cannot find the link to the tach article on Jeff's site???
withthe price of these units bringing what they are now , and if you want one bad enough, it may be worth while to get a rebuildable one and pay the $125++ to get a tach fixed. NONE of the individual circuit boards , or other tach parts are available new or repro for the trucks. DAVE
