rpm electronic counter
Posted: 30 Nov 2021, 23:05
Good evening everyone, here is my first post; before writing it I checked that there was no useful information available...
Why this post? Simple, a friend, who is about to restore a fulvia, asked me: "you, who are electronic, can you fix my rpm counter?"
Well... I started separating the components and testing the galvanometer... and it actually works.
Not without effort, I managed to separate the pcb from the galvanometer… the surprises began...
transistor and capacitor burst...
I have recovered the transistor code (I don't know if I will have to install equivalents) but I have no information about the capacitor.
I guess it has been connected incorrectly. Would anyone be kind enough to help me?
Do you have a list parts, is there a manual service instrument? I try to post some photos...
Many thanks and best regard.
