I'm the proud relatively new owner of a 1968 camaro. The only problem is that the dash lights will not work. I have signal and engine lights just not dash. Are they series or parallel in nature? Should I replace all 4 or is it a wiring problem.

Thanks
Tony

They are in parallel. Try turning the headlight knob once it is pulled out, it may have a burnt spot on it.

If this effort fails, and heater controls lights come on, then could be burnt bulbs, a loose ground wire on the cluster, or a blown INST fuse.

Oh, welcome to the Club, hope you enjoy your membership.
