Have a 720w 8 bar style led with 3 drivers. Woke up this morning and 3 of the 8 bars are just barely lit up while the others are running like usual, tried driver on other bars and it works fine. So assuming problem is in the 3 way harness that connects the 3 bars to 1 driver Took apart and white neutral wire has a little discoloration right where it connects to the light on all 3 bars. Any ideas? Could the neutral not getting a good connection cause the leds to just barely light up?
