Repairing the Yamaha Outboard Tachometer Buttons

It’s always getting me a while to write my next post (this doesn’t mean that i don’t make things in the meanwhile) but the time is limited and keeping notes, photos videos etc of what i’m making in order to post them to the community it takes me almost the double time from just making it. My passion of making things stems from my very early years and became bigger and bigger with the power of internet and projects sharing. I like helping people and sharing ideas the same way as i’m learning from other’s and makes me a better engineer. So i’m not going to stop sharing projects even if my time is limited. 

The repair of this gauge came to me while i was trying to track the running hours of the outboard engine. As i was pushing the buttons to change the display of the Yamaha outboard tachometer ( 6Y5-8350T-83-00 ) nothing was happening.

The first think i did was to remove the gauge from the panel it was mounted on and inspect if there is a visible crack or something that let humidity or water to pass in and oxidize the contacts of the buttons. Once i found the suspicious crack on the enclosure i was now almost sure that humidity was absorbed inside the device and the contacts of the buttons were oxidized. The second challenge was to find how this enclosure was secured together. The enclosure had a type of plastic rivets in the back side which i dared to cut with the cutting pliers and finally got access to the insides. 

I decided to demonstrate this project creating a video log instead of writing it a blog post just to see how it’s going and be easier for the reader to watch the repair as an entertainment video.

If you like my video please let me know by liking the video and subscribing to my channel. If there is interest on viewing my projects on videos i’d try in the future to make more video posts than blog posts.
