Posted August 12, 200519 yr comment_133886 My speedometer and tach are not working properly.. They dont show you you speed or RPM's however they do light up properly. I checked the speedo cable that goes into the tranny and its fine. Any suggestions on where i should look or what might cause this?

August 12, 200519 yr comment_133919 Hard to say exactly. The speedo is mechanical and the tach is electrical. If the cable is okay then there is most likely a problem in the speedo itself. Did you check the make sure that the cable is connected to the back of the speedo? If so, remove it from the tranny end and spin it by hand and see if you see any movement on the speedo. If not the cable is probably broken. Trace the hookups on the tach and make sure it is connected correctly. The fact that they light up has nothing to do with their function.
