Another Buell Temp Sensor question

[jl551c]

06 Uly: I noticed my fan wasn't coming on while shutting off my hot bike. Pulled out the Buelltooth and sure enough the fan works as it's supposed to with the Buelltooth. I figure it must be a temp sensor located on the rear head. So, I bought a new sensor, made a removal tool, (someone can have it when I'm finished), removed the old sensor and immediately noticed a difference in the connector, (not the 1/2 inch bolt that is the temp sensor, but the connector). Here's a pic:



Do you think I can just cut off both connectors and swap the old, "male push-in" connection onto the new sensor harness and replug it in? I really don't want to mess with the connector on the bike side since there's hardly any room to work with.
Also, is this harness wire a single wire or wire strand? At 80 bucks a shot I don't want to do any exploratory surgery.
Thanks

Free to good home when i'm done.

ward: your 2006 ulysses has the old style temp sensor. the part # for same is 32564-99Y or 32564-99YC. it was delisted about 4 years ago and superseded by the latch plug model you bought. there are still some new floating around online including ebay. swapping the old style bullet connector over to your new ETS can be done but is tricky.

The fan doesn't always HAVE to come on when you shut off the key. It only does when it's over the set temp in the Fan Settings section under ECM Parameters.

You can check the temp sensor itself by looking at the "Live Data" screen on the same ECMDroid/Buelltooth you checked the fan with.

I would double check the Buell factory part number first to see if it's the same sensor. Then, sure I guess? Make SURE to check it's data output the same way you should have checked the old one before you bought the new one:upset: $$

FYI, temp sensors and O2 sensors are sensitive to wire length, keep it as close to the same as you can.

Good luck!

Edit: Lunatic looked up the part number for you, sounds like your GTG:up:

I love making my own custom tools, my temp sensor is fine (I think) but I’m headed out to the garage to make a temperature sensor tool!!!

Swapping the old style over to the new style would be too hard for me to do due to the short length of the female side of the bullet connector. I think cutting off the new latch type connector and splicing the old male bullet connector onto the new harness might be the best option. I"m just wary about length, (like Cooter mentioned), solder? splice? Nature of the wire, etc.
I'll first check to see if I can find the old style online.

Cooter, the fan never comes on when I shut down, even when it's really hot. I can't remember having a problem with the fan not coming on before I swapped to a race muffler and reprogrammed the ECM with Buelltooth, but not sure since I wasn't always paying attention to the fan.

Well, looks like i made a bonehead decision of 80 bucks by buying a temp sensor before verifying the old one was bad. (I spent thousands of dollars for a college degree and learned less in some classes than I did today changing this sensor for $ 80, so all's not lost).

Temp sensor reading at ambient temperature. It's 90 degrees here in California today.

The chart which shows that the ohm meter readings I made closely correspond with the chart, which also tells me my original temp sensor is likely good, which also tells me I made a bonehead mistake, which also tells me I need to continue troubleshooting.

All is not for waste when it comes to the sensor removal, however. Looking at the sensor wire I have chafing in a couple of places. They're not bad enough to prevent end to end continuity, but now I can wrap it in some kind of heat resistant tape or something to prevent a problem down the road.

Well, that's good news and bad news but also, you've educated some of us.

I guess I don't understand the problem. Are you concerned the fan does NOT come on when you turn the key off?

Does the fan work while riding?
Is "speed based fan control" checked under ECM Parameters?

IMO, I'd the old sensor back in after I heat shrinked the insulator to repair the chaffing (no need for 'high temp'), return the new sensor, buy $80 worth of beer because the wife will never know, and start to diagnose it
Have you recently played with the programming? The ECM parameters get downloaded with the fuel map if using ECMDroid and that includes the fan settings. There are a LOT of programs with the fan settings backwards... Check that first.

Then go for a ride and check the actual bike temp with Live Data.

Then you'll know if theres even a problem.

Report back here and lets see what's up! If anything it's a great excuse to go for a ride:angel:

Yes, the problem is the fan has not been coming on after shutting the key off. I have 2 Buells and the 07 SS sings like Dolly Parton when I shut it off. I'm pretty sure it's been coming on while riding. Sorry for the vague answer on that, (I"ve been away from home for a while and have been meaning to get to this for a while). I reprogrammed the ECM for the Race Muffler that I installed with a Race Muffler program. It'll have to wait for Monday, but I'm gonna hook back up with Buelltooth and double check the temp parameters and the "speed based fan control" setting. I"m pretty sure I didn't check the box enabling "speed based". Backwards? Wow, haven't heard that one before. OK, and I'll check with Live Data as well.
Thanks and I'll get back to ya Monday.

I don't like the "speed based" setting, the fan noise is annoying to me, but its an easy test to see the ECM activating the fan properly anytime above 20MPH (or so).

Ya they have the ON temp below the OFF temp. Lame, but check it. Good luck and report back:eagerness:

Will do, thanks.

It would be working fine if you were still on the, right coast !
