69 911E total restoration almost at the finish line. Hazards and turn signals were working fine but in repairing the hollow plastic shaft of my hazard switch I had to pull the shaft out turning on the flashers while my glue dried. I forgot to turn them off after the 5 minute epoxy cured and they were left on for an hour. No worries as the batteries were on a tender. When I remembered that I hadn't turned them off they had quit working. First thought was the flasher relay had puked but the turn signals still worked and I believe they use the same relay. Any thoughts on where to start?
