matt6306 Posted February 11 Share Posted February 11 I needed to get a gauge cluster for my 68 cat but i was only able to find one for a 68 riviera. I went ahead and bought it but it doesn't seem to work real well. most of the circuit on the back lines up with the old one but it behaves weird with the light switch. When i turn on the headlights the gauge lights turn off and the dimmer switch brightens and lowers the generator light. is there a way i can make this gauge assembly work? Also it seems to run kinda shakey and bogs off the line. Link to comment Share on other sites More sharing options...
EmTee Posted February 12 Share Posted February 12 My initial reaction to the weird behavior that you describe is that there's a poor or missing ground to the cluster. 2 Link to comment Share on other sites More sharing options...
JohnD1956 Posted February 12 Share Posted February 12 most of the circuit on the back lines up with the old one did you compare the 2 in the factory shop manual electrical diagram? But the speedometer is mechanical so it soundclike the unit will need some servicing. Link to comment Share on other sites More sharing options...
