Almost everyone has heard someone quip that modern trucks are computers on wheels. Increasingly, technicians are keeping their hands clean as they work on circuitry and electronic diagnostics.
The changing maintenance and repair landscape also is reshaping a technician’s toolbox to include the necessary tools for efficient, quality electrical system diagnostics and repairs.
“Products inside the tool boxes are changing,” said Travis Hopkey, director of marketing, Phillips Industries. “Digital multimeters, battery testers, terminal crimping tools and heat guns or torches now are very common. These tools help technicians get to the root of the problem instead of simply masking it or guessing.
“Gone are the days that a good technician could diagnose a problem just by listening to a component,” he continued. “Because advanced technology is so prevalent on new trucks, the industry is becoming more familiar with diagnostic equipment and how to use it. The technicians need to understand things like voltage drop, amp draw and how to make the best wire connections.”
The first step toward having a well-equipped electrical shop is to staff it with well-trained technicians who are up to date on the latest trends.
The fact that the industry no longer refers to service technicians as mechanics points to the market demand for savvy individuals who can confront today’s electrical problems.
In this sometimes complicated repair field, it’s best to start simple when training. “The basic rule is to make sure you’re using the right tools for the job and master a few easy techniques to make connections and repairs as waterproof as possible,” according to Chris Cammack, brand manager, Grote Industries.
“Having the proper tools to do the job is something every technician should take pride in. Crimpers, cutters and diagnostic equipment are essential for doing the job right,” he said.
For example, probing wires no longer is a common practice. “People still do it, but most good shops are using the right electrical testing equipment,” said Hopkey.
Technicians wishing to gain electrical repair knowledge can look to manufacturers for assistance. “Many truck manufacturers have troubleshooting books that they create for a specific truck, including electrical troubleshooting,” said John Nolan, western region corporate fleet training manager, Grote Industries.
Nolan also recommended that you establish a mentorship for technicians who are learning electrical repair. Not only will this ensure that today’s diagnostic tools are being used correctly and effectively, but it can be a key safety asset as well, since electrical work has the potential to be hazardous.
“For example,” Nolan explained, “The fan on the motor can hurt someone severely, so technicians need to understand how it works.”
Other safety equipment needed in the electrical shop includes safety glasses and ladders. “Ladder safety often is overlooked,” said Cammack. “Make sure that you are using the correct height ladder and that it is on stable ground. Do not overreach.”
Once you have safety mechanisms in place, see that the tools you are using to complete repairs are right for the delicate nature of the electrical system. “Vehicle electronics are very sensitive,” said Hopkey. “Voltage spikes and heat can kill much of the onboard electrical components.
“From digital voltmeters to battery testers and electronic trailer diagnostic equipment, shops need the right tools to help them solve their customers’ problems and gain their trust.”
Electrical components also are sensitive to bad seals and contamination, so keep things protected. “It is more important than ever to make a proper electrical repair, and this means a sealed connection with the lowest resistance possible,” said Nolan. “Quality matters here.”
The increasing presence of road chemicals and the prevalence of electronic technology mandates properly-executed connections.
It’s important to have access to the right tools and to keep your knowledge fresh and your repair work efficient.
Since today’s electric systems are becoming increasingly complex and sensitive, it behooves you to make the investment in quality electrical tools and training now so you can establish yourself early as your customers’ go-to for electrical work.
