Anyone having issues with the green output connection block? Ended up changing my wires on mine and hooked the unit up and L2 to neutral went to no volts. Checked blue wire at stud to neutral and had 120volts. Pulled board out and found cold solder joints on L1 and L2 connections and L2 having no connectivity. Is this common? I just resoldered it.
Would this be a good idea to reinforce the connection? If I remove the varnish coating and reinforce from the bolt all the way down with solder? (where the red is)
I just don't want to have it crack out and cause a burn out on the board when I'm pulling some high amperage on motor start up
Not really a cold solder joint (I.e., bad soldering during assembly), rather “stress cracks” from vibration during use. I wouldn’t say its common but have seen plenty of these over the years on a variety of devices.
You did the right thing by reflowing the solder.
