So I plated my WR450, I installed a Vapor Speedo, a brake light and a horn. My problem is that I hooked the vapor speedo up to the battery, as well as the horn and the tailight all seperately to the positive terminal. Everything was working fine, speedo was working and the horn and the taillight. I figured I might clean up the mess, so I soldered the vapor positive wire to the horn positive wire and the horn stopped working! I cut the wire and made them seperate again both going to the positive terminal. Still horn is unable to work. So I hooked the battery charger up to the horn only and it will work just fine, but when I have it on the the actual battery terminal it wont work. Any suggestions?
