I am not very electronically knowledgeable. I usually plug things together until they work or the smoke comes out. I recently bought some SSRs from Jameco (LCA110). The datasheet did not come with a basic circuit, so I just hooked up the input side to the 5v rail of a computer power supply and the other side to the same power supply but through a resistor to an LED. My goal was to test my connections before hooking it into a circuit to ensure I was connecting it properly.
I did not use a resistor on the input side and was getting a flicker on the led. I wanted a steady on state. I put a 100uF cap across the power/ground to smooth out the power, but it did not help....now for the really not smart part. Since the first one wasn't working well, I decided to test other SSRs to see if they did the same thing. Most of them did nothing.
My questions are, did I blow out all of the internal LEDs by not using a resistor on the input side and is there a way to test if they are still working?...again, I am getting nothing from the output side in both the DC and the AC/DC setup.
If an oscilloscope is needed, Then I'm out of luck.
Here is a link to the datasheet:

Thanks. Hopefully I gave enough information.
