• The most important part of an electric truck is the control that operates the electrical components. Knowledge of this control – how it works, and how it operates the other components – is vital to maintenance and service.
• This class is designed to teach you how the EV T15 Transistor Control operates and how you can diagnose and troubleshoot problems with the control. The EV T15 Control consists of a control card and the electrical components it operates.
• The card monitors power demands and responds by controlling the power applied to system components. The control operates a series of switching devices that enable it to direct the power load across different electrical circuits.
• These circuits control everything on the truck from the traction motors to forward and reverse drives and accessory devices So your knowledge of the control system, the components it operates, and how to diagnose and troubleshoot conti·ol problems helps you to keep a truck in top shape and avoid down time.
