Hi all. I’m installing five 751D switches to Five PECO motors/solenoids. The power supply I’m using is an old laptop psu (18.5V DC, 3.5A). My issue is when I have more than two switches and turnouts wired up they pulse on and off at startup as if there Isn’t enough power. After it pulses for a while everything clicks into place. I add a forth switch and turnout. It has weaker pulses and doesn’t stop. The instructions say 12V but I have tried that and they wouldn’t turn on at all. What am I doing wrong? Is it possible to install a CDU with the 751D switches?
