    where to connect 2000 Yamaha 1200 xl ltd exhuast temp sensor

    I recently picked up this ski and the exhaust temp sensor was left dangling and for the life of me I can't figure out where it goes. Here is a pic:

    Its is most likely disconnected if it has the Cat removed and the resistor installed. It plugs into the side of the e-box where the three connectors are just to left in your pic.

    Thanks beerdart, I found the resister and it test out at 1000 ohm. I have a problem where the warning alarm goes off and reads w. temp. Would the engine still start if the lower exhaust pipe sensor is bad? It looks like one of the wires broke off...

    probably an open water temp sensor... 10K ohm resistor to by-pass or I have some used ones

    I chipped it with a 10k resister and it came alive now all I have left to do is clean out the old fuel from the carbs and am good to go!

    Any luck getting those carbs off. I have the same ski in FL that someone practically gave me because it needed a new starter. After getting the starter replaced I had a little delay in putting everything back together. It's taking me much longer to put Humpty Dumpty back together now after the memory fade. I was going to pull the carbs to clean and rebuild but couldn't get to some of the bolts on the bottom side. I spent a couple days of feeling around and dropping tools in hard to reach places and decided I'd just try running cleaner through them . bad idea?

    Is there an an easier way that I'm not aware of or is it extremely difficult to get the carbs off?

    I found that the farthest back oil line was broken and had to replace it, could've been bad...

    I've just about got it all back together and can't remember if the exhaust temp sensor was ever connected. I broke the bottom tip off what I think is the electrical bypass for the D-plate mod while searching for a place to plug the exhaust temp sensor plug in, super glued the broken tip back on and have no idea if it will still work. I could pull the headers back apart to see if my D-plate theory adds up but I don't really want to pull it back apart again if there's an easier way...

    sorry if this is in the wrong thread, first time poster.

    You have to pull the exhaust out to get the carbs off.. its the only way
    Also not sure what you are trying to do, but pull exhaust, pull airbox. Disconnect cables, pulse lines, and fuel lines then there are 2 10mm bolts near the choke plate on each carb and a total of 4 5mm allen screws in between the carbs.. its pretty easy.
