I bent a pin on the back of this as seen in the picture. I have a spare speedometer with the circuit board but there is a break in the "Green" area where the pencil is pointing to. Is there a way I can repair the pin by soldering it? Or should I switch out boards? I just wasn't sure if the "Green" area is a Vital Component. Thanks for Any Help.

 

Bent pins sometimes are not a problem unless it gets detached. Have you tried to straighten the pin? There is some forgiveness in that style of construction. Gently try to move it back to vertical. If it comes loose, the base of it can be soldered back to the copper trace.
The gap in the 2nd board can also be soldered. Gently scrape away the solder mask and solder a short piece of 18-20 ga. wire across the gap. Circuit boards are very easy to solder, but also heat sensitive. Use a pencil style soldering iron with 60/40 (or 63/37) rosin core solder. If you aren't comfortable soldering, I would be glad to fix it for you. Feel free to contact me if you desire assistance.

 

Thank you very much Randy, I will try to solder the pin back to the board.

 

If you have an ohmeter you can check for continuity on both sides of the scraped area. Check for it on the bare copper areas.
I've heard you can uses 2.5 millimeter screw in the back of the pin to secure it to the board. I'm not sure where to get 2.5 mm screws though, maybe a hobby store?

 

For loose or detached pins, I have also threaded a small screw through the back of the circuit board and into the pin. That has worked quite well for me and avoids the risk of damaging the board with solder. Of course, you have to be real careful in threading that screw into the pin but it's worked for me every time I've done it.
