[Roadsters] Cigarette lighter problem

My WAG's:
What gage wire are you using for the + to the battery, and firewall?  I seem 
to recall that the thinner the wire the more resistance (actuall less 
conductivity) it has and therefore potential overload on a fuse.

Also, have you checked that the ground at the firewall is making good 
contact?

Lastly, have you checked that the prong that holds the lighter when it's 
depressed isn't overly tight?  That prong is designed to expand with the 
heat from the lighter element, but sometimes they can be overly tight 
causing the lighter to overheat before it will expand that prong enough to 
release the lighter.  It should be tight enough to hold the lighter against 
it's spring, but loose enough that once it heats up it allows it to pop out 
of the prong (not the holder).
