On my 1992 International model 9200 truck, with Detroit Diesel Series 60, my speedo died long ago and recently the tach also quit. From probing the cluster wires with an oscilloscope, it looks to me like it's communicating via serial data. The cluster had two rows on dip switches, looks like some kind of settings. Any idea what those switches do? Is there a better place/forum to ask this question?
