Description
Because electrical sparks must be able to jump 200 times a second through the contact point of an automobile voltage regulator, this tiny part is platinum tipped. The platinum, at $1,334 a pound, makes the part one of the most expensive, ounce for ounce, in your car. Here Florence Naum of Ford Motor Company's Ypsilanti, Mich., plant looks with a magnified, critical eye at selected samples to be sure each is in perfect condition to assure long wear.
