Anybody can help me to trouble shoot this problem.<br />Tachometer does'nt work. Is there any procedure<br />to test the unit if working or not. Thanks.
Hook up a hand held tach.on the back of the dash tach.If you get an accurate reading take out the tach.& do the float test.Drop the tach in the water,if it floats it's good.If it sinks buy a new tach.
