I have been taking the dash out of my 54 Mercury to repair the gas gage. Someway I have either blown a fuse or disrupted the flow of power. IT has two fuses that I can find under the dash but there has to be more. Where? Everything in the dash worked except the gas gage until I began my moving things around. No power to the ingition switch, lights, dash, etc. Any suggestions appreciated. Any web sites to find the wiring diagram
