Tach and Crise Control

[coltonkid]

On my '91 Cruiser the tach only goes up to approx 1100 rpm, no higher. The cruise control doesnt work. Does anyone know what the cause of these two problems may be. Are they related or controlled by the same thing????

the cruise on mine only works if i have a light shorted to the body, i have read some stuff about it having to have a certain resistance. does the engine seem to rev higher then 1100?

yes the engine is reving up with normal driving but the tach doesnt register the engine speed above 1100
