Ok I bought this regal 86 2 months ago and no gauges works, I changed the fuel sender and speedometer cable and bulbs, nothing works. Checked fuses, took apart the cluster and cleaned and bend the metal parts in on everything so it will be tight, but headlights and turn signal works and check engine light works and that is it. What am I missing?

Find the ground for the gauge cluster and make sure it is grounded. If the dash has ever been removed make sure the dash is grounded to the body.

Look at the wire bundle coming from the connector(s) coming from the gauge cluster. The ground should be a black wire and come out close to the cluster with an eye terminal on it. It should be screwed to a metal part of the dash.

Check your gage fuse. No power, no work.
The lights you mentioned in the first post have their own power.

Hey bud, have you figured it out yet? Let us know. I guarantee what these guys are saying about the ground, is your issue. I had this same problem on mine as well. Ground was the problem!

PJNJ201 I have not fixed it. I was looking for the black wire and I can't find it, It looks like the person I bought it from changed stuff around

Damn, i see. If you still have it apart, is there any way you can post some pictures of what it looks like behind there? Wires, harnesses, connector etc. and also just out of curiousity, what kind of shape is that green connector film that sits on the back of the speedo in?
