Expertise for Complex Equipment
When a heavy-duty truck develops a difficult fault, finding the cause can take more than a quick scan. Terry Conklin is a heavy-duty diesel specialist, consultant, diagnostician, and educator who helps fleets and technicians work through challenging equipment problems. His background includes ASE certification, electrical and air-conditioning certifications, and training in compressed natural gas (CNG) and electric vehicles.
Based in Port Orange, Florida, Terry offers on-site consultations and training through Energy Transfer Technology. When an on-site visit is not practical, over-the-phone and screen-based diagnostic support can help narrow down the issue and identify useful next steps. Terry works directly with clients to schedule consultations and training around their needs.
A Diagnostic Question, Answered
Question: “A truck has an intermittent electrical fault. What information should I gather before seeking help?”
Answer: Note when the fault occurs, any warning lights or diagnostic codes, recent repairs, and the conditions surrounding the problem. Record what has already been tested, too. These details give a diagnostician a clearer starting point and can make remote troubleshooting more productive. Every case is different, so avoid replacing parts based on a code alone.
Have a question about diesel systems, electrical diagnostics, CNG, EV technology, or shop training? Relevant questions and conversations are always welcome. Share the symptoms and context, and Terry can help determine whether a call, screen session, on-site consultation, or training is the right fit.
