So I recently installed a horn on my 85 K100RT. It doesn't have any guages, turn signals or anything so I wanted to add a horn to get it inspected. I took the gas tank off and used a multimeter to find the wire that originally went to the horn, clipped it off and ran a new wire to the horn and it worked fine. Put it all back together and now the bike won't start. After messing with it I noticed the TPS no longer clicks when you turn the throttle. I took the connection off the top and put the red multimeter probe to the positive terminal on the battery and used the black probe to check all 3 connections and each read roughly 12 volts which isn't right. Then I connected the black probe to the negative terminal and used the red probe on each connection and all 3 read zero volts. I'm much more mechanically inclined than electrical so I could use a little help here. I can't imagine what I could have done when connecting the horn that would have impacted the TPS
