Re: Honda CBR 250R

fan does not kick in anymore. was stuck into jam for over 40 minutes and saw 6 bars on heat first time in 4 years....

turned off the bike. got it back to normal . took and alternate route and reached office.

coolant levels are good. looks like fan has conked off else the switch that engages the fan... fuses good.
hope its not big thing that failed..

My radiator fan failed recently and it was found that the relay has failed. I got robed for a radiator fan relay change today. The SVC Ppl said that there are 2 relays and they changed both. I have no idea about it though. Including a waterwash the bill was 763Rs.

Any insight abt the fan relay? Could help in future and may be to other xbhpians.

am going for a change tomorrow. will keep you posted. my fan failed just an hour back and am suspecting relay...

Sorry that you had to see 6 bars of temp in your CBR. I suspect that the fan is at fault here. When the relay failed in my bike, the fan was running nonstop until the power(battery) is disconnected.

Quoting the below post from [MENTION=35815]krish2778[/MENTION], which shows that fan should kick in if anything fails except the power line. Hope yours is a similar issue below and nothing big.

So guys, I had reported i had this problem of fan not working, so we found out the problem. The issue was that ,the socket of the fan sensor that is for drawing current form the battery directly was loose and not conducting. And this particular socket was at the least accessible spot under the air filter box , so they had to strip all the bike plastic panel parts to get to there, hence the delay. Now the fan is working fine. Took her for some city riding, the gauge was at 3 bars, then i stopped at a place and switched on the engine kill switch and ignition on and after 5 seconds the fan started roatating. So that problem is over.

Also i got to learn that the cooling system(fan) of the cbr has a direct connection for power source form the battery. and that particular socket is independent of the rest of the wiring of the bike. The service technitian was kind enough to show me that in the wiring diagram and also explained it to me in detail. I really liked the service from there. And they have 3 senior mechanics for the cbr.

The showroom is John's honda, Trichur. Kerala members can make use of their superior service.

Cheers
Ride Safe

There are two relays to the left of the bike you can look at it by peeping towards the left side of the handlebar, one is fuel pump and one is fan relay. Usually they replace both because their "sixth sense" tells them, if one fails, the other one too could give up. Ultimately, if you got both of them replaced, nothing to worry, make sure you get the old good relay and keep it as a spare.

Re: Honda CBR 250R

any idea on cost of the radiator fan ? worst case if its gone....

It's 2600 INR for radiator fan motor assy.

Relays for sure!

Around 260 Rs.

@theironhorse99 what Arvind said. But what I am surprised is the location and the ease with which water and dust can spoil these fuses. Talk about irony, I mean, Honda provided cover for fuses which are under the seat, and have provided spare fuses, good in fact. But they've omitted the cover for those two fuses which are exposed and which are critical for the fuel pump and the fan. What even more ironic, is they have a transparent rubber boot under the same relay box, but not over it, kinda funny if you ask me.

Cheers!

Re: Honda CBR 250R

That's a good point. I guess they think that relay will be affected only through contacts and at given location water cannot flow down due to faring protecting it

.

But what am surprised is, given that relay is at fault here, then what is the reason to give the radiator fan a direct supply from battery if a relay fault can stop the operation of fan.

As in my case a faulty relay caused the fan running continously which I guess it did work as expected.

Relay has a movable armature mechanically hinged at one point. There is a fixed contact point. In a layman's language, when free end of armature touches the fixed contact point, the circuit gets completed and fan kicks on. In your case when your relay got kaput, the armature failed to retract to its position, got into contact with fixed contact point and hence completing the electrical circuit and your fan was continuously on. However, in most of cases the armature fails to do its job when relay goes kaput - breaking the circuit permanently.

Re: Honda CBR 250R

Just tore apart a relay to see the mechanism down there. It's the same type as stated above. Attaching some pictures.

You can refer the below post for relay position and cost. For me the labor charge is Rs.66 for changing the relays, so the amount looks fair considering they usually charge more for water wash than outside shops.

Ram

Rs.66? Vs Rs.300 I was definitely robbed. I will take it up to them.

Share the break up if possible. Thanks.

I was aware of one relay but not the second one. I didn't get the faulty relays since I was more than Ohk that they surprisingly gave my bike back in short period. Here in my town they don't have any spares for the 250r. Usually they take weeks to change any parts. They don't even have throttle oil with them. pathetic! I procure spares either from Madurai or chennai.

Good news is I'm riding to chennai this weekend for a full service. So I'll get everything checked. The fairing is cracked due to a fall so I have to change that as well.

Thanks for the info.

Re: Honda CBR 250R

This was my bill and labour charge for relay change, you can see that labour charge is 66 for me too but the way they arrived is different as the time taken to do this once faring is removed is kind of 15 mins.
