"where did you have to dig to fix the tach"
The fuse behind the right air vent.
The uh... uh... This thing...
overload protection relay
Red 10A fuse was blown since 2 previous owners ago.
I removed my air vent to get to it easier. seems to have been a bad idea, I cannot get the vent back on correctly... part of the plastic has snapped from the fastening ring.
I had a few people tell me that the instrument panel must have been replaced from a newer model and I shouldent have a tach. Those few people were incorrect.
