 ====== Broken Horn Bracket ======
-\\
+The horn bracket that is mounted along with the key switch between the cylinders has been known to cause meltdowns. \\
+The fact of the bracket breaking (due to being loose, vibration, age etc,) isn't the problem (electrically speaking). \\
+The key switch terminals are bare ended (no insulation). \\
+Should the horn bracket break, the horn will (most likely) swing down & rest on the back of the ignition switch for awhile, shorting the terminals. \\
+The subsequent dead short heats up the wires, melting them and triggers the carnage shown below. \\
+At this point, the motor is dead, no lights, no nothing. You're stranded on the side of the road, wondering just what happened. \\

 See the 'before' pic of the horn / switch brackets below (taken ≈ 8 months prior to my catastrophic event). \\
 The ends of the ignition switch wires were heat-shrink'd immediately after this pic was taken. \\
