 +====== Horn ======
 +This is a rebuild of the stock Delco Remy horn from a 68 XLCH. \\
 +There are horn rebuild kits available, but they are pretty simple in design and a good cleaning may be all that is needed. \\
 +The repop one from J&P Cycles is on the right (3rd pic below). It has 2 wire connections as opposed to the single wire connection on the original horn. \\

 +A bench grinder was used to grind the rivet faces off flat. You can also use a drill bit that is larger than the hole in the rivets to drill off the face. \\
 +Then you can use a center punch to knock the rivets out or pull them out of the other side with pliers. \\
 +Then separate the halves and clean up all surfaces with sand paper or a wire wheel. \\

 +You can check the continuity of the coil but be careful not to break the wire. \\
 +Use some 400 grit sand paper to lightly resurface the contact points (you may have to push the lower contact down to get the sandpaper in and out). \\
 +After everything is cleaned up, reassemble the horn and test. \\
 +There is a small screw on the back of the horn, you can make slight turns on it to adjust the horn for the best sound. \\
 +Keep in mind that too far one way or the other and the horn will not work at all. Use pop rivets to put the horn back together after a thin coat of RTV. \\
 +Ensure that you don't get any sealant on the vibrating plate or it will not work. \\
