Your going to need a multimeter to test the circuits.I would start by going over all the work that was done to replace the head gaskets. Sounds like maybe a ground wire was left off.

If you smell something burning it is the head.U need to remove the info panel. When u disconnect the info panal and the head comes on. Replace the info panel if not replace the speedo head its fryed.

I would be looking for loose wires/grounds etc under the hood where you did the head gaskets. If everything worked before the head gaskets were replaced then something was left undone or pinched. Did you check all the fuses for power to both sides of them?

I know all the answers im disabled now. Did u unplug the info panel yet? Your goin to at leat a test light or we cant go on. They are cheap just make sure it has a bulb so we can check voltages. These are common problems for a cadie.
