Tach sending unit

Sending unit is located on the driver sider inner fender,it looks
like a black plastic cylinder about 2 in. tall and has electrical wires
under.It is right behind the glow plug relay(square plastic black box).Quick fix for the problem:when you locate the unit,remove
the cap(like any bottle cap),place a piece of cardboard inside the
cap and reinstall the cap,if you feel pressure when you put it
back on its OK,otherwise the cardboard piece is to small it has to
create pressure so the electrical connectors are tight.Tach should
start working again.Problem is caused by the old glue that is
supporting the connector pins,it gets old and the connectors are
"sinking in",so,by placing the cardboard you create the suport
for the pins...you will see that when you open the sending unit.
