have a 2000 dyna low rider. after charging battery (hd battery) and putting back on bike everything electrical seems to work as should, lights, signals, horn, can hear the fuel pump engage. problem is I flip run switch on then press the start switch and I get a faint single click, sounds like from somewhere under seat area or around where the horn is located. did not confirm charge on battery assume it is good if other electrical is working. greatly appreciate any advise or expertise. been in garage all winter, getting nice out again...must.....have.........Harley
