If you find yourself in a car garage in Cameroon and hear the word "LATTRE," you'll immediately know they're talking about an automotive electrician. This is the person who spends their days, using a test screwdriver, trying to solve electrical problems on your cars or trucks. But what role do "LATTREs" play in our modern vehicles? In the 1920s, the first vehicles had a maximum of 100 meters of electrical wiring. Over the years, with the addition of various systems to vehicles, the length of the wires continued to grow, reaching 1400 meters per vehicle in 1999. The direct consequence of this was that a small short circuit could cause a fire that would completely destroy the vehicle. In the 2000s, with the introduction of safety and sensor systems, manufacturers gradually introduced CAN bus, or "Data Bus." The information (data) transmitted by CAN buses is managed electronically. Therefore, it's no longer enough for a technician to simply determine if there's a signal on a bus; they also need to know the signal strength and its destination. The old-fashioned test screwdriver is no longer sufficient. It's becoming essential for every technician to purchase a multimeter and receive training in its use. If you want to become a "Modern Technician," @KAS Trucks currently has a promotion for the first 10 multimeter buyers. You'll receive a discount of 15% with one hour of training on its use.
