Is your battery fully charged? When my battery was not fully charged the stock relay wouldn't make the blinkers flash. A fully charged battery helped, but what totally solved the problem was replacing the stock flasher relay with a modern electronic unit (about $9). The electronic units do not require a fully charged battery to make the blinkers flash. Ed
