Hello All: Back after several years, and am working on the bike again. It was derelict for over 20 years and purchased with clear title. Frame up to get it resurrected. I have noted many opinions on Turn Signal Flashers. Mine work fine with an original relay, and with a new one I just purchased. Original wiring harness. Front and rear signals work fine and shut off with manual switch on the left handle bar. My comment is this: Front turn signals will work with the rears disconnected. It will even work with only one disconnected. May help someone trying to work on them.
