Spider alternator output

[Ed Lutz <montjuic@domain.elided>]

Anybody know the output of the alternator used on a 1974 Spider? Are there 
bigger ones available and if so, how do I tell them apart? I'm interested 
in putting a pair of 100/55w halogen bulbs in and need to know if the 
system can handle it.

Thanks,

Ed
