i was testing my friends horn on a 2000 venture, that was not working , i had to remove it from the mount which also had the battery grd wire attached in same place, went to start the bike and all i got was a sound like a low battery, well like a dummy i discovered i had not reattached the grd wire and was touching the frame but not connected, well i reattached the cable and turned the ignition key and it starts with out hitting the start button i do not know where to start ,, by the way this was an after market horn that had a relay i do not know if that had any thing to due with this problem,, thank ahead of time for the help.,, by the way it is a the yamaha shop and they cannot figure it out yet..
