Fluval Pro LED Lights - PWM Walkthrough

[fred73]

One thing you could do to start, use your volt meter and see if you get DC voltage on the 2 contacts in the first image. I'm guessing that's the power fed to the LED's. Check the voltage when the lights are full power and check again when lights are set to 50% brightness.

If you do get a DC voltage on those contacts, leave the GND probe from your meter on the black terminal in image 1 and then with positive terminal touch each of the 7 contacts from the "processor" board to the LED board. Mark down any voltages you might see on the different pins and then change brightness of light and test them all again to see if any changed.

Hi Rob 

Thanks for all your help, really appreciate

I will try to remove the black  silicone and crack it open this afternoon

 I saw that on planted tank some one did the same but with the version 2.0
