    I don’t think it’s an issue with D5, since (as far as i know) D5 isn’t necessary for the OSSC to work. It is a transient voltage suppression diode. It doesn’t do anything under normal workload, but provides an alternativ route for high voltage ESD pulses (to protect the ICs from damage). It’s a protection device and under normal circumstances the OSSC should work perfectly fine without it (same for D3 and D4)!

    You can get a BOM (= bill of materials) for the OSSC here:

    https://github.com/marqs85/ossc_pcb/raw/v1.6/bom/bom_full.xls

    It should list all components and their markings.

    If you are not even sure how to check for continuity via multimeter: maybe you should ask someone with some more experience in electronics for help!?
