Lost instrument pannel power and power to ignition accessory in fuse block. Removed gauge fuse, checked out ok, have 12 v to fuse. No power to ignition accessory port on fuse pannel. Had fans hooked to ingnition accessory port thru toggle switch yesterday but today no power and no gauges. Fuel pump comes on as it should for a few seconds when ignition is first turned on. Engine starts and runs. Have power to everything else on fuse pannel. Never had oil pressure gauge (probably bad) but had temp, volt, and tach before this problem. Have not driven to see if speedo still works or not.

Any suggestions where I should start looking? Grounds, relays???
