Visual inspection of a solid state regulation assmbly on a few models of alternators won't provide much insight into the ability of a particular Focus application alternator to last 10K or 200K mi. Practially every alternator uses a different regulator assembly, there are hundreds of styles. The regulator is a control device that does not see high current. As I mentioned, the Ford rectifiier assemblies use a flawed crimp design that is not shared with the aftermarket modular units. The high power power rectifier that can see 100A peak current is what generally faiils, not the control regulator.
