I have a problem with my 1995 Sportster XL 1200. The lights go on but the signals, and horn do not work and when I step on the brake the brake light doesn’t light up. Also when key is turned on the lights are on but a clicking sound clicks every 4 seconds. We replaced the turn signal control module.
The clicking sound is coming from a breaker. You have a dead short to ground. You need to look for the breaker that is tripping. Then, find the corresponding wire that is grounding out.
