Yeah, I like using 'black box' building blocks when building a project..
But, sometimes, it's the black box that fails you.
I have opened up a few sealed boxes a few times over the years..
And sometimes, I was surprised at how few parts were inside,
or how cheaply the assembly was made..
I wonder if this AC SSR problem was as simple as me, just not understanding
how it should be connected to run on DC..
I have to admit, I Googled using AC SSRs with DC and found zilcho usable info..
