Having trouble getting blue LED's on booms 4 and 6 to light. Red LED's on boom one light. Lights are from Quadrocopter. I have two sets of 3 red LED's on boom one split to one jst going to three way splitter in the hub. One set of 3 blue on booms 4 and 6 going to the three way splitter in hub. The three in one out splitter in the hub is connected to PCB board on S1. PCB board is connected to the FCB via servo cable to top side of servo1 brown wire to inside on FCB and brown to J7, red to 5v, and yellow to J6 on the PCB board. Power is from +/- pads on bottom of FCB. Trouble shooting. Tested three to one splitter in hub. Red lights will light on any of the three in's. Tested lights work. Plugged 2 cell 7.4 volt direct to lights. Reds light blue will not. Plugged 3 cell 11.1v to blue lights and they work. Tested for shorts on PCB board found none. LED's on PCB board light up. Kopter Tool setting are set for low voltage flashing and red led's flash blue never light up. Anyone have ideas? Picture attached.
