As we complete our resto on a '74 TR6, we again having fun with the electrics. This time we are unable to get the hazard lights working and therefore unable to get the signals working. When we pull the new hazard switch we get a dim lighting of the front LED signal lights and no lighting of the rear LED signal lights. We did find that we were getting 6.5 volts at the rear signal lights but obviously not enough to activate the hazard switch or illuminate the lamps. Our first thought was a lousy ground. The grounds in the vicinity of the lights appear OK but we were wondering if there might be some other ground not in the vicinity of the lamps that might need attention that we don't know about. Any ideas to move things along are appreciated. Thank you in advance.
