Working temperature of transistor regulator is abnormally high or low (outside range >70°C or <10°C). Transistor regulator defect. / First determine whether truck’s operating environment and conditions are normal! Allow truck to regain a normal temperature and attempt normal use. If fault persists replace transistor regulator.
