Just a thought guys on the metal strip. Could it be that the heat 
escalation in the sun is sufficient enough to expand the metal in that 
"fuse" and cause it to open or separate the circuit?  Ask someone to 
help you with a little test. Turn on the ignition switch and  jump it 
with a pair of alligator clips and a length of wire just to see if it 
kicks on or use a hairpin and rubber handled pliers to hold it to 
complete the circuit for a split second just to confirm? It might point 
you in the right direction and.I don't think merely making the 
connection for a split second will have any negative result or damage 
any circuits. Good luck.
