A faulty ignition module can cause a vehicle to overheat. The vehicle may run and then lose power suddenly due to a rise in the engine's temperature. Once the engine cools, the vehicle will start and run until it overheats again.
In two days the Dow Jones industrial average fell by 25% (ending on Black Tuesday, 29 October). The volume of stocks traded set a record that was not broken for 40 years. When it finally reached its record low in July 1932, the Dow Jones had fallen 89%, and it did not recover to 1929 levels until 1954.

But in 1929, the bubble burst and stocks started down an even more precipitous cliff. In 1932 and 1933, they hit bottom, down about 80% from their highs in the late 1920s. This had sharp effects on the economy. Demand for goods declined because people felt poor because of their losses in the stock market.
