Ok so I've wired up my BRS t5 retro kit and some days it will work by cycling up to 100, holding, then back to 0 as programmed. Then the next day it just wont turn on period. I double check my VSP on the 2016 but don't get any voltage readings at all, even when manually setting on and off. I've searched countless threads here and through google and they all lead up to using the Neptune cable (which I am) testing for controllable voltage (which I have, but cant control it) replacing said cable again with a new one, and am now to this step....thinking the brain box itself being intermittently faulty. Any help or ideas on what to do next? I currently just have the light coming on and off with no dimming using the EB8 port.....but I'd like to have my control ability back again. Thanks for all that help!
