I was just completing some minor work on my 65 when I noticed that I lost power to the radio, electric fan, dash lights, courtesy lights taillights and brake lights. All other electical works fine good gauges, tach, headlights, front turn signal and starts and runs fine. I have had my Painless wire harness in for about six months and 250 miles all was working fine . Checked my grounds and they are all connected and solid. Does anyone have any suggestions to the cause. This has me for a loop.
