Got a pair of these neato Lvl Lok 500 series. One works perfect but the other only passes signal in bypass.
I've checked for shorts to ground and haven't found any so now I'm attempting to trace the signal. I'm having trouble understanding the signal flow on the schematic, notably Ub send and Ub Ret. There's a couple different spots where these Ub pop up with different numbers and I'm getting lost.
Big question is does Ub send go to Ub return or is it the reverse? Schematic attached. Thanks!
