Maybe you should leave ambient_light at 1, and mess with the default 
texture instead. That way, all textures which specify an ambient will 
get it, but you can set the default to 0. If you still want a way to 
globally control your ambient values, make a multiplier variable:
#declare AmbMult = 0.15;
...
finish {ambient Val*AmbMult}
