Thermal Imaging–Small Investment Saves Customers Thousands
Here is a thermal image before and after shot of K21 and K23 starter contactors. Please note—amp draw was fine. Thermal imaging uncovered a problem with L2 and 158°F at 175°F. Further inspection of the contactors showed contacts inside the starter were severely burnt.
Thanks to the thermal camera this problem was taken care of before a more serious issue took place (fire, burnt wiring, burnt unit due to contactors welding closed, shutdown of unit, etc). Notice the big difference in temperatures with the new contactors.
