Hi folks,
Been having a few overheating issues with my Txt 280 (non pro); I'm hoping someone can give me some further guidance. Already replaced the fan motor once but has failed again quite quickly. I've been looking at the voltages being produced and I suspect I have a failed voltage regulator. Measuring the AC voltage supplied to the fan motor rectifier (the Leonelli box screwed to rad cowl) I get 17~18v on idle and up to 60v with the bike rev'd up. The DC voltage out of the rectifier is hovering around 25~28v at idle. This to me suggests the regulator isn't working as I should always be getting a fairly stable 16~17v AC (guessing here) supplied to rectifier what from I have read in other posts. I have had the regulator out ("Transval 415 box" hidden up in top of the frame behind the coil and CDI) to clean the contacts etc but this doesn't seem to have have helped.
- If the regulator has gone, can it damage the fan motor / fan motor rectifier, or anything else for that matter (bike still runs fine, apart from fan motor)?
- Using the wiring diagram linked below, where it indicates a resistance, is this between what the resistance label is pointing at and earth?

Any advice would be welcomed on the above.
A tip for anyone looking to replace the fan motor who has the "Mitsuba PM-3" motor. This motor is common to a lot of other bikes it is just difficult to find which ones. With a bit of eBay research I've found that Honda fit this fan to the CBR125, VT125 (Shadow) and XL125 (Varadero) from around 2004 onward. There are plenty of CBR125 fans listed and all relatively cheap. I've just picked up a 2010 one for £10 delivered. I will confirm it does the job when it arrives!
Cheers
Sam
