I have a 2004 chopper and have been having issues with the headlight. After riding for a bit, after stopping and restarting the low beam will not stay on. High beem works and sonetimes if I flip high to low a few times it will go on. I changed the bulb, checked all connection and all looks fine. Checked the voltage regulator and that was good also. I am hoping its not the EHC, but dont know what else it could be. Any suggestions on what it could be?
