Have a 1945 GMC 1/2 ton. Parked it last fall all the lights worked. Started it up last week, checking lights noticed that signal lights stopped blinking with head lights on. Have made the park lights into signal lights. Have 6volt system,led 6volt flasher,6 volt led bulbs in rear lights, with a 6volt led third brake light. Has anyone any ideas what is wrong?
There is no global warming in Alberta Canada.
