Diode check function has its limits. Bad diodes generally short out.

https://www.tvrepairinfo.com After having actually checked countless diodes over the corse of my profession, there was as soon as a time where I located myself needlessly unsoldering diodes to evaluate them as a result of the truth that elements in parallel with the diodes under examination would certainly provide me complicated analyses, yet after understanding nearly all of the negative diodes I experienced had much less than an ohm of resistance, I discovered myself utilizing my ohms operate as opposed to the diode check feature when I had an analysis that really did not make good sense.
