I Broke A Connector

[fontanaman]

The last time I checked the valves on the 17ES, I broke the a cable side connector that plugs into the thermostat sensor, part number 5YP-85790-00-00. The temporary was wire ties. Works fine for now but next time I go in I want to make it right.

So what is the part number for the cable side connector that plugs into the thermostat?

Chat GPT query said for the thermostat connector, 5YP-85790-00-00, Yamaha often uses Sumitomo MT series 2-pin female connector 6187-2801 6187-2804 conveniently located on Amazon.

They come in multi pack so this give me an opportunity to practice releasing the pin and speaking of pins suggestions on pin releasing tools are helpful because I need one.

After looking at the Sumitomo MT series 2-pin female connector 6187-2801 6187-2804 I don't think it fits the thermostat connector.

Check with Eastern Beaver and Cycle Terminal, match up the picture with what you have.... the FJR I fixed has left the barn, so I can't help much. Not sure, might be same as fuel tank connector??

Fontanaman,

Where I worked, I had a great collection of pin extraction tools. (I bequeathed them to my replacement dude at work when I retired.) In all cases, I would find the original connector manufacturer and call/ email their tech support for the correct extraction tools. Most OEMs would provide these extraction tools free for the asking.

Once you look into the end of a Sumitomo connector, you'll see how the pins release... normally they use all the same terminals, so it's a matter of a sharp pick to pry over the plastic lock, then pull the terminal out by the wire. You can re-use the terminals, just insert into the new connector. Best you have a new one in front of you and you'll see how the terminals lock into the connector. I have several Sumitomo connectors here, can take some pics.
