Hi Guys,

I would like to know if anyone knows where I can get the wiring diagram for the new 2010 model TXT300?

I have the wiring diagram from the 2005 model but there is a significant difference in the wiring in the section of the thermostatic switch and the regulator section.

Reason for me asking for the diagram is that my cooling fan constantly runs after the bike has reached operational temperature. The fan does not come on immediately only when the coolant has reached the point where the fan should kick in but then the fan never stops again. I have checked the obvious like water pump working, enough coolant in the radiator etc.

My theory now is that the regulator might possibly not supply the full 12V to the fan and therefore runs slower which is why the fan needs to run constantly to try and cool things down.

Strange thing is that when I stop the motor to take a breather and then start the motor again which is after 2minutes or so the fan does not run immediately but takes some time after I am riding again to switch on again. I am a bit confused by this.

The bike was bought brand new and I remember that in the beginning the fan switched on and off intermittently like it should do. So something has gone wrong and I am trying to figure it out.

So if anyone knows where I can get the wiring diagram for the new TXT300 then it will be greatly appreciated.

Thanks Marius

My guess would be a faulty thermo switch that kicks in at a lower temperature than it should. If the fan was spinning at a lower rpm than it should surely you would notice it? I do know that at one stage my fan was slowing down and making squealing noises, a bit of oil in the fan motor sorted that out though.

Marius,

I'm not positive, but the 07' Kokusan may be more in line with your 2010: http://www.trialspartsusa.com/diagrams/KokusanDigital2005Pro.jpg .

Not sure if you have the Ducati diagram rather than the Kokusan.

Hi Jon,

Thank you for the info. I actually have that diagram. It is listed as the 2005 model but I don

OK I went for a ride this weekend and the fan worked flawlessly. Switching on and off as the radiator temperature raised and cooled off again.

I was really baffled by this. This was definitely not the case a week ago.

So the only explanation I have for this could be because I was taking connectors off and plugging them back again when I was measuring voltages etc. that I possibly corrected a bad contact in the process.

I shall keep on monitoring the fan to make sure everything is OK.

Probably the cure. I like to use a little "Dielectric Tune-up Grease" (Silicone grease) in the connectors to prevent future corrosion and help with waterproofing. You can get small tubes of it in auto supply stores and the small tip of the tube is perfect for squirting in the connector pin holes. I also use a Dremel tool with a small sanding tube to lightly clean ground points in the electrical system and add a little tune-up grease to the contact area.

If you use a pressure washer on your bike, avoid the fan/radiator area with high-pressure soap which can drive corrosive soap into the fan motor and the high pressure stream can bend over the thin radiator fins, blocking off air flow.

Hi Jon,

Excellent advise given there. I shall make sure I treat my connectors to prevent something like this happening again.

Thanks
