The CLC red light needs to be on. Chances are if it’s an old power supply that you have a bad power supply. Even though your meter shows 5.09 vdc dosnt mean it’s clean power. Check the voltage with your mete on AC. If you have more than 1 vac on the power supply it’s junk. With the CLC board with only LCC 11 plugged in you should have the light on! If not bad power or bad board! I’ve seen new boards be bad out of the box.
