1995 Softail, sometimes it will start normally, but most of the time I hear the starter make a clunk and not turn the engine over. When it does not start, it makes the clunk noise and the lights dim. I have tried jumping it with a strong jump box and it does the same thing. The battery tested good. Either solenoid or starter, not sure if it would make the clunk noise with a bad solenoid. Any thoughts would be appreciated.
