Every day, healthcare experts and data analysts update models predicting the spread of coronavirus to show the extent of the human tragedy—the number of lives lost, patients hospitalized, and unemployed workers. Despite the intense scrutiny, much uncertainty persists.
Within the automotive sector, COVID-19 is a massive, once-in-a-lifetime disruption, and the situation is changing rapidly. To gain more clarity about the pandemic’s potential impact on the light-vehicle aftermarket—encompassing parts, accessories, and tire sales—we reviewed both past and current trends. First, we looked at previous crises to quantify how demand, revenue, and other aftermarket performance indicators typically change during a downturn. We then considered the current global health crisis and created scenarios showing how the aftermarket might evolve this year, as the pandemic abates, and over
Alternators are used in modern automobiles to charge the battery and to power the electrical system when its engine is running.
Until the 1960s, automobiles used DC dynamo generators with commutators. With the availability of affordable silicon diode rectifiers, alternators were used instead. This was encouraged by the increasing electrical power required for cars in this period, with increasing loads from larger headlamps, electric wipers, heated rear windows and other accessories.
The modern type of vehicle alternators were first used by the military from WWII, to power radio equipment on specialist vehicles.[i] Post-war, other vehicles with high electrical demands, such as ambulances and radio taxis, could also be fitted with optional alternators.
Alternators were first introduced as standard equipment on a production car by the Chrysler Corporation on the Valiant in 1960, several years ahead of Ford
