|  Hi Oliver,
    You have a cable coming off the back of the generator to run the tach
 mechanically. The easiest place to start is to unscrew the cable from the
 tach gearbox at the back of the generator and pull the inner cable out. If
 its broken, there's at least part of the problem. Alternatively, reach up
 behind the dash and find the cable going into the back of the tach. Unscrew
 it there and see if it turns while the engine is running. Pull it out to
 check if its broken.
    If all is well there, you may have a problem inside the tach. I'll leave
 that for others to comment on, as to rebuilders and such.
