Basically ive a 78 cb550 k model cafe racer. Since last year ive went through 3 units First ons failed which i think from memory its was a wiring issue second one seemed to failed for the same reason i then bought a third from another company due to me thinking the quality was bad of the First two third ons fitted and charging well fine all summer this year bike is not charging again and the fault seems to be the same as before. Anyone any idea what might be causing this
