wiring problems

glynor

On my 1978 corolla sr5, suddenly a bunch of electrical quit working. The components include the interior light, oil press. gauge, amp gauge, engine voltage gauge and tach. Also, when turning key on, there are no dash warning lights or illumination lights. I have cleaned all fuses that I can find and checked fusible link for continuity, also cleaned bat. ground- to-block. Alt. charging at 14+ volts, battery is one year old. If anyone has a suggestion on something else to check, please let me know, I am out of ideas. Thanks for your help! gly
