Instrument Lights Not Working
The insturment voltage regulator is just for the guage power. I would think that either the petintiometer (sp) in the headlight switch might be bad as everything else is working I am posting a link to a diagram and it has number 930 with a line going to a terminal. Check to see if you get power out of that terminal. If so then look at the wire feeding to the cluster. If you get power to the cluster then You have either a bad ground or the circuit board is bad.
