Here's the scoop, I replaced my water jacket cover gasket the other day and there is this little wire that is connected to a little brass plug that goes into the block right next to the #1 spark plug. Well, I accidently hit that wire and broke it off at the base of the plug, so I soldered the wire on and thought I'd be ok. I took the boat out to test the seal on the water jacket cover and in my throttle control it kept a constant beep going like an alarm was going off, I am assuming that the solder didn't hold? What is this part and what does it do and where can I get one cheap?
