  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Buddy's TE 250 fan constantly on

I just added my switch to the connector that goes to the switch in the hose. I didn't want to cut it, since I'll probably add it back in, so I just used suitable gauge wire, soldered to the switch, and stuck the other (obviously stripped) ends in the connector. Then I taped it all up and used a zip-ty to secure it to the frame.

You could also use a tap splice or something similar to make it a little more neat.
 
Jimmy's buddy's bike doesn't have a switch in the hose like the newer 250/310Rs do. The ECU turns the fan on/off.

Still, it'd be pretty easy to wire up. or even toss the fan- once it's determined the ECU is getting good info.

hmmmm- looks like the 2010 TE310 & TE250 have different manuals.... and of course, I can't read the wiring diagram of the 250 easily. But it looks close to the 310 so let me throw a few suggested places to look at.

[later edit: Actually, a quick & dirty sensor test may be to just unplug it- if the fan stops (cold bike, key on, engine off?) then the sensor is bad. <--- yeah, do that first, that'll tell you fast.]

1st, try pulling the orange wire w/ a green stripe off of the fan relay (this may involve a lot of hand-waving if it is bundled in a multi-wire connector, as is likely). If the fan continues to run, it's probably a bad relay. (option 1 test: unplug the relay and test the 2 main terminals: open circuit means it's probably good; option 2 test- else just plug in another relay and try that one). This tells you it's the relay that is bad.

If the relay passes the above test, we have more of a mystery: put your money on a bad temperature sensor (hopefully, it's not a bad ECU). It's denoted as a WTS (water temperature switch) or #33 "coolant temperature sensor" on the wiring diagram. I'm guessing it is supposed to be at infinite ohms (ie, open) when the water is cold; you may find it closed (50ohms or way less) at any temperature- meaning it's bad. Just buy it and cross your fingers.


Try these two test and let us know what you find. BTW, my TE310 has been running fine, with the fan removed, in 90° F temps; although that's close to my personal riding limit- even while wearing an evaporative vest.

good luck.

For the 2011 TE310 I found the "Water temperature sensor" in the manual, pg 3, item 2. [Reference: Part #8000A6736 (USE PART # 8000H3649) $9.99]. My fan would rarely come on and I just blew a hole in a radiator hose! New hoses on the way, so I guess I should be sure to add a new temp sensor as well. The more I read, the more it seems like others have had the same issue.

I boil the rad fluid all the time, so maybe that fan should have been on a lot more! Even then, I might need an on/off switch. To be continued.
