[SOLVED] Unkown surface mount component

[blackkatt]

Hello to everyone here. I was hoping that someone here could identify what this component is at L1 and L2. I am thinking that they might be some sort of inductor, but since there is no markings on them, I have no real clue.

Its a ferrite bead (a binocular one). It won't be faulty (not much to go wrong with that).

In the first picture you can see damage to the pcb, which was caused by a relay shorting out. When the relay did this it also burned the trace to the L1 ferrite bead. So that is why I am a little bit concerned about it.

You can snip the wire and replace it with an approximately similar gauge of wire, to reassemble L1/L2 if you're concerned.
Make sure the gauge is not less (higher is ok). You can check the gauge with a micrometer, or just manually compare it if you're in a
store that sells wire. However, that's only necessary if the wire is damaged (check to see if it is broken). From your second photo, it looks
nice and thick and clean; unlikely to be damaged. In a good design, the fuse would be damaged, not the L1/L2.

Thank you for the advise. There is continuity across both L1/L2, so I will just put them back in as is. Now to just fix the traces and get some new relays.
