More scientific approaches to forecasting have included the use of a devide called a barometer, used to measure changes in atmospheric pressure. Generally, low pressure means the weather will suck.
Logic Probes
Fast, accurate diagnosis of auto electric/electronic problems is a big part of our daily shop routine, isn’t it? We’re all spending a lot more time and money on electrical test equipment and training than we used to.
Animated Suspension
The willingness of Honda’s design engineers to follow that simple rule has made the Honda Accord a hot selling car in this country for the past several years.
