<VV> circuit breaker

[Padgett]

My 66 convertible has a circuit breaker that does not appear on the 
schematic. Was wondering if it might be for the power top motor (from 
factory). It is on the support that runs between the battery and the 
engine. What looks like a #16 wire is running from the battery to it and a 
#12 wire that connects to the main harness is on the same long stud. The 
other end has a red #12 or #14 that goes separately back through the shroud 
grommet. Does anyone know ? Wiring for the power top does not seem to be in 
the factory manual.
