After a year of looking at the outside temperture indicator always affected by the radiator heat, decided to move it. Thanks to the person who told me where it was months ago, but it finally hit me for the ### time looking for it. Behind right front wheel. Photo shows it already out of the hole it mounts in, if u look there, maybe u won't miss it like me. Was surprised to find the sensor wires having a connector link, by the right foot fuse door. So I pull the sensor, and search for a connector. Surprise, it is the same ones that are used on the older Goldwings, of which I just happen to have some. www.electricalconnection.com sells all kinds of connectors used on differant bikes. Made up an extension cord, for the sensor connections. Then ran it up by the steering, down by the air horn, and zip tied to the frame where ever I could reach. It loops over the front shock, coming down behind the right side sitting head light, then exist around the edge of the radiator; finally zip tied behind the screen web of the directional. Now it may be hot from the sun beating on it, but cools down to real tempertures, and remains there while riding.

how does it compare to a regular thermometer when just sitting in the driveway? I have never checked mine for accuracy.

I usually subtract about 4-5 degress and figure close enough..
When is says.. 97 degrees or 100... I'm not going to quibble.. when it says 40 degrees and it's really freezing.. that makes a difference.. |

I always felt that at best, it was reading the "heat index" and not true ambient temperature.
But I like your new arrangement. |

Cool beans, G03. I always mentally subtract 4°-6° but would rather have the sensor in a spot unaffected by engine temp.

Since mine always reads at least thirty degrees high after warmup, I'll need to do this. Right after buying the scoot I used spray crack filler to muffle the tilt buzzer, and doing so cut off airflow to the temperature sensor and it's never read correctly since!

sorry about the web site wrong list, had an extra s on it. corrected it. Hitachi conectors are used on some bikes, search under connectors.

I have a MP3 250. My temp reading has never worked right. It reads Low instead of an actual temperature. Do you think it is located in the same place as your 500? If anyone could give me some help with this I would appreciate it. I looked through the trouble shooting guide and see that temperature readings are causes for many problems.

Mine seems to be reading correctly. By its location on the bike, I can't really see how it can be affected by the radiator, since there is a cover that prevents air flow behind the radiator. I am not sure how that works out on a 500, tho.
I can, however see that it is directly affected by the warmth that comes up from the pavement though. It may not be completely accurate for ambient temp in that case, but it would be more accurate for indicating that you may have an issue with cold pavement (freezing). |

If anyone could give me some help with this I would appreciate it. I looked through the trouble shooting guide and see that temperature readings are causes for many problems. As I said in a previous post, interaction from the radiator is less likely than pavement radiation. This is an opinion, of course, based on the fact that I have had the covers off a couple times. There is a cover in the back that is behind the radiator which forces the air to flow towards the fan, which draws it through. Air would not freely flow through the radiator towards the sensor. ![]() I believe the bump you see in the circled area is it. Note the plastic around and behind the radiator.

Thanks for the extra pic! That helped. I guess I am going to try to buy a new sensor for the temp and see if I can get an actual temp reading besides Lo, unless anyone can think of another reason I would get this.

Bad connection, or possibly pulled on the sensor wires when removing it, braking a wire? Use an ohm meter across the sensor wires, disconnected. If no ohm level shows, it is broken sensor.

Does anyone have pics of how to disassemble the body work around the panels around the right foot fuse box? I can take it apart just fine, just scared about putting it back together.

Clem, what is the issue? Did you do anything? or did the sensor just stop working? If the 250 is same as 500, there is a connector plug just by the right side foot panel for fuses. It does not have a lot of wire on it, and I suggest sticking a length of tape or something on it before pulling apart, because it will fall back inside and be a bear to find. Mine would just pull down to the top edge of the opening, so it was tough to grab.

I have found it where you said it was. The wire is not long enough to come out for me to get to the male/female connection that are shown in the pics. I am scared to pull on it to try to get more wire out. So I was thinking it might be easier to remove the body work then pulling on a wire that I have no idea what it is connected too.
I bought the scooter this way used. I think I saw the temp reading one time and have not seen it since. |

What is the point, we all know how cold or warm we are (I hope), I like the temp sensor telling me how warm I am when my nuts are freezing, it's nicer like when the doctor says "you might feel a slight scratch" or when he rams his finger up your arse "discomfort" or the policemans "good evening sir" while wearing that evil grin.
The temp gauge is the ultimate comforter, almost political and a born liar with only nice lie's. I like it. |

Here is a thread by Luthorhuss getting the panels off a 250. Oops! Anyone know how to fix this?

I think I saw the temp reading one time and have not seen it since. https://modernvespa.com/forum/wiki-workshop-manuals The MP3 service manual will show you the procedures for removing every part and in what order. Their organization is a bit wierd, so it might help for your to print it out and put numbers on the sections starting with the Radiator Cover which is the first piece you take off (others, feel free to add comment if I missed something). As you can see from my earlier post, I have been there (and further in, I might add). It is not super-complicated, but you might want to install some soundproofing in your garage if you get frustrated easy. If you'd like I could post a few pics of mine as I removed the parts up to and including the leg shield. |

Thanks. Pics would help a lot. I was foolish enough to buy a manual off ebay, not knowing that it was posted online and a better copy then the one I received. I just have to have some courage!

A word on screws....
Luthorhuss has some excellent posts on keeping your parts in order. Check them out. If all else fails is that most of the bolts are easy to locate and figure out where they go. Screws are in two basic kinds. Flat-ended self tapping and sheet metal. Guys, check me on exceptions, but the sheet metal screws go in the speed nuts (those are the metal springs with a threaded hole). The self-tapping kind go directly into plastic. |

@Fuzzy-I just looked at the thread by Luthorhuss and my jaw dropped when I saw all those panels on his floor. HOLY COW! If my scooter had looked like that, I would have crapped a Miata. Impressive work from Luthorhuss!

Fuzzy wrote: Great pics. Thanks, you make it look easy. After the last pic, I found that three of the four screw posts on the back of the legshield had cracked. This generated a four letter chorus that would probably have melted cast iron. When I got done freaking out, I went to the Ace Hardware across the street and picked up some house blend plastic repair epoxy. Glued back the broken part and fixed the other cracked posts, along with some filleting for strength. Two years later and I removed it again to install a radio signal cable. The repair was as I left it. Probably stronger than the original. |

I believe when I wiggled it and tugged some, gained about an inch more of wire. It is mixed with wires in center by the frame, but wiggling it to the side does add some. It was just at the top opening, I used needle nose pliers to hold one end, and pulled on the bottom connector. Just do not let it go without something on it to pull it back.

Thanks all for the advice and pictures. I am going to brave it out and give it a try. Worst thing that happens is, the Piaggio dealer gets a little more money out of me for my 9,000 mile service.
