Something about Zener diode. I have found that the door lock switch of
my '98 Hyundai Accent has been damaged by water (sealing issues). I used
Wurth Contact OL to remove rust but one of the components of the board
has got broken while I was trying to remove the rests of the product
with a piece of paper. I believe I can carry out the soldering work but
I cannot identify the broken component. My searches (according to
Testing and Distinguishing Zener Diodes Overview, content source:
lead me to believe it is a zener diode, but what kind? There are no
markings on it.
I have thought about asking the local shop to give me a selection of the
most common types and go the trial and error way, but I am afraid I
could fry other thing... So, could someone guess, by the pictures of the
board, what kind of component I need to have all the doors of my car
closed in one move like in the old good times?
Thank you in advance.
